Twenty-four satellites orbiting the earth broadcast timing signals which are freely available to use. The positions of these satellites are constantly changing. The GPS receiver tracks signals from all satellites visible above the horizon and uses measurements from all satellites more than 10° above the horizon to calculate exactly where it is on earth. This is called the GPS position. A GPS receiver can receive signals from the GPS satellites when it is almost anywhere on earth. The receiver is accurate even at high speeds and accelerations. •Extremely long battery life; around 40 hours of operation from one set of AAA alkaline batteries. (2 second update, trickle power mode) •No operator setup or adjustment required; the only operator control is the On/Off switch. •25 x 25 x 4 mm (1 x 1 x 0.2 in) patch GPS antenna with sensitive 12-channel GPS receiver chipset. •Available in two versions. These are identical except for resistance to water: The GPS 4500 is fully waterproof and is designed to be mounted outdoors, for example on the roof of a vehicle. The GPS 4400 is not waterproof and is designed to be mounted indoors. •An MCX connector for an external GPS antenna and a connector for an external power supply (GPS 4400 only).

Bluespark Technical Overview 25/3/03 D.Swarbrick Bluespark is a battery operated GPS receiver that transmits the NMEA data to a remote host using the Bluetooth protocol. The schematic is divided in to four sections: Page 1. GPS RF front end and Receiver. Page 2. GPS processor and flash memory. Page 3. Bluetooth transceiver/processor and flash memory. Page 4. Power supplies and logic translation. GPS RF front end and Receiver. GPS signals on 1575.42 MHz are picked up by the dielectric patch antenna (P1) and amplified by the LNA, Q4, whose bias is controlled/switched by Q1. Q3-A and Q3-B form a high side comparator sensing the voltage across R38 when current is drawn by an external antenna applied to J2. Q2-A and Q2-B buffer the comparator output and switch pin diode D10 on while switching Q1 off, thus selecting the external antenna while shutting off the LNA and hence the internal antenna. Note that the external antenna is applied after the on board LNA and assumes an active gain in the order of 18-30dB. (3V source, 5-20mA operating current) Q14 provides the processor with a level translated, active low flag to indicate that an external antenna is applied. U6 is a low noise 2.8V regulator providing power to the RF section and is controlled via the RFPC0 line from the processor when using trickle mode. Q15 and Q6 are also controlled from this line and switch off power to the external antenna when in trickle mode in order to conserve battery power. Signals from the selected source (either int. or ext. antenna) are presented to FL2, a SAW filter on 1575.42MHz to remove out of band signals before being input to U4, the SiRF RF IC. The GPS TCXO, Y5, and resonant circuit C96, L7 provide a clean, stable oscillator source. The SiRF RF IC uses a superheterodyne principle with a VCO local oscillator on 1565.97MHz and an IF of 9.45MHz. 2 bit sign and magnitude data is sent to the SiRF processor while RF power and AGC control signals are received. GPS processor and flash memory. The GPS processor is based on the ARM7 CPU and runs a 1.8V core with 3.3V I/O. It is a true system on a chip and contains at least the following functions: 1Mbit SRAM, Boot ROM, Real Time Clock, GPS DSP, Battery backed SRAM, Beacon DSP, SPI bus, I/O unit and Dual UARTs. Refering to page 2 of the schematic, U10 is a voltage monitor providing an active low reset to the processor if the 3V SiRF Vcc drops below 2.8V. D6 provides a non-return charging path (when the GPS is active) for the 3V MS Li-Ion battery (BT1) which supplies the RTC and BBSRAM via U18, a 1.8V regulator, when main batteries/ext power is absent. When either the internal batteries or the external power source is available, an alternative path is provided via D1 and DC_IN. Q7-A provides a level translated active low flag to the processor when external power is available thus allowing mode switching and the benefits of full power GPS to be realised. SIRF_TX and SIRF_RX are the main UART outputs (non-inverted TTL, 57600,8N1) carrying the NMEA data. Bluetooth transceiver/processor and flash memory. U3 is the BlueCore 2 single chip Bluetooth system incorporating 2.4GHz transmit/receive and baseband functions. Data originating from the GPS is presented to BC_RX, the BC2 UART input, for processing and eventual transmission as RF. Timing for all processor and RF synthesis is provided by the 16MHz crystal Y1. When transmitting, the outgoing balanced RF is first matched and converted to 50 ohm single ended by inductors L2, L3 and balun Y2. Filter Y3 provides harmonic and spurious output rejection before signals are passed to the chip antenna. Note that DC is provided to the push-pull output section of the BC2 via the balun. In receive, the reverse order of operation applies – signals from the 50 ohm chip antenna are first filtered (out of of band signals) then translated to a balanced input, under control of the internal T/R switch. U5 is a 4Mbit 1.8V flash memory that directly interfaces with the BC2. Q13-A and Q13-B buffer and translate the PIO ports to provide LED indicators for low battery (DS1, Red) and Bluetooth status (DS2, Blue). Power supplies and logic translation. 3 x AAA cells provide the main (int) power and this supply goes via the reverse battery protection device, Q5, to the 3V switching regulator, U13. Low battery status is monitored by U9 which outputs an active low to both the SiRF and BC2 processors, via D5, when level drops below 3.2V. J3 is the external 5V DC input socket. D2 provides reverse polarity protection while U11, a precision shunt regulator, conducts if the supply goes over 5.7V, saturating Q16 and shutting off Q17. This open circuit over voltage protection serves to protect U13 but is not intended to duplicate the full automotive load dump already provided in the 12V to 5V cigarette adaptor. When the On/Off switch, S3, is pressed, Q9 turns on and provides an enable to U13, the 3V switchmode regulator. This provides power to U7, which outputs 1.8V to the BC2. The BC2 then outputs a logic high to PWR_ON, switching on Q8-A and effectively latching the power switch on. If the BC2 is already powered on then pushing the switch S3 again will turn on Q8-B, providing the BC2 with a logic high on PWR_OFF and initiating the power down sequence. Q18 and Q19 allow the BC2 to control the 3V GPS supply, saving power when the Bluetooth link is lost or yet to be acquired. Q10-A and Q10-B provide inversion (2 stages), buffering and level translation for the SIRF_TX to BC_RX data path, with a tap mid way to the flash/program adaptor plug, J1. Similarly, Q11-A and Q11-B provide the same for the BC_TX to SIRF_RX data path. Q12-A and Q12-B provide translation from the BC2 GPIO to allow the SiRF processor to be reflashed. A tap between these devices also goes to J1. J1 is a diagnostic/test connector accessing most of the control and monitoring points needed to flash either the GPS or Bluetooth functions (even simultaneously).

The distance from the EUT's transmitting antenna where the exposure level reaches the maximum permitted level is calculated using the general equation: S = P*G / 4πR² S max = 1mW/cm², P = 0,75 mW, linear power gain relative to the isotropic radiator = 0 dBi = 1 (numeric gain), R = distance in cm Solving for R, the 1mW/cm² limit is reached in a distance of 0,24 cm to the transmitting antenna. Because of the construction of the device, it is impossible that the user gets that close to the transmitting antenna. Please contact us if you have any additional questions.

There is only one transmitter which is driven by identical input parameters concerning these two parameters. Only a different hopping sequence will be used. For this reason the check of these RF parameters in one op-mode is sufficient. 2 Frequency range of a Bluetooth device: Hereby we declare that the maximum frequency of this device is: 2402 – 2480 MHz. This is according the Bluetooth Core Specification (+ critical errata) for devices which will be operated in the USA. This was checked during the Bluetooth Qualification tests (Test Case: TRM/CA/04-E). Other frequency ranges ( e.g. for Spain, France, Japan) which are allowed according the Core Specification are not supported by this device. 3 Co-ordination of the hopping sequence in data mode to avoid simultaneous occupancy by multiple transmitters: Bluetooth units which want to communicate with other units must be organised in a structure called piconet. This piconet consist of max. 8 Bluetooth units. One unit is the master the other seven are the slaves. The master co-ordinates frequency occupation in this piconet for all units. As the master hop sequence is derived from its BD address which is unique for each Bluetooth device, additional masters intending to establish new piconets will always use different hop sequences. 4 Example of a hopping sequence in data mode: Example of a 79 hopping sequence in data mode: 40, 21, 44, 23, 42, 53, 46, 55, 48, 33, 52, 35, 50, 65, 54, 67, 56, 37, 60, 39, 58, 69, 62, 71, 64, 25, 68, 27, 66, 57, 70, 59, 72, 29, 76, 31, 74, 61, 78, 63, 01, 41, 05, 43, 03, 73, 07, 75, 09, 45, 13, 47, 11, 77, 15, 00, 64, 49, 66, 53, 68, 02, 70, 06, 01, 51, 03, 55, 05, 04 Annex - Additional declaration part according FCC 15.247 for Bluetooth devices Page 3 of 5 pages 5 Equally average use of frequencies in data mode and behaviour for short transmissions: The generation of the hopping sequence in connection mode depends essentially on two input values: 1. LAP/UAP of the master of the connection 2. Internal master clock The LAP (lower address part) are the 24 LSB’s of the 48 BD_ADDRESS. The BD_ADDRESS is an unambiguous number of every Bluetooth unit. The UAP (upper address part) are the 24 MSB’s of the 48 BD_ADDRESS. The internal clock of a Bluetooth unit is derived from a free running clock which is never adjusted and is never turned off. For synchronisation with other units only offset are used. It has no relation to the time of the day. Its resolution is at least half the RX/TX slot length of 312.5 μs. The clock has a cycle of about one day (23h30). In most case it is implemented as 28 bit counter. For the deriving of the hopping sequence the entire LAP (24 bits), 4 LSB’s (4 bits) (Input 1) and the 27 MSB’s of the clock (Input 2) are used. With this input values different mathematical procedures (permutations, additions, XOR- operations) are performed to generate the sequence. This will be done at the beginning of every new transmission. Regarding short transmissions the Bluetooth system has the following behaviour: The first connection between the two devices is established, a hopping sequence was generated. For transmitting the wanted data the complete hopping sequence was not used. The connection ended. The second connection will be established. A new hopping sequence is generated. Due to the fact that the Bluetooth clock has a different value, because the period between the two transmission is longer (and it cannot be shorter) than the minimum resolution of the clock (312.5 μs). The hopping sequence will always differ from the first one. 6 Receiver input bandwidth and behaviour for repeated single or multiple packets: The input bandwidth of the receiver is 1 MHz. In every connection one Bluetooth device is the master and the other one is the slave. The master determines the hopping sequence (see chapter 5). The slave follows this sequence. Both devices shift between RX and TX time slot according to the clock of the master. Additionally the type of connection (e.g. single or multislot packet) is set up at the beginning of the connection. The master adapts its hopping frequency and its TX/RX timing according to the packet type of the connection. Also the slave of the connection will use these settings. Repeating of a packet has no influence on the hopping sequence. The hopping sequence generated by the master of the connection will be followed in any case. That means, a repeated packet will not be send on the same frequency, it is send on the next frequency of the hopping sequence. Annex - Additional declaration part according FCC 15.247 for Bluetooth devices Page 4 of 5 pages 7 Dwell time in data mode The dwell time of 0.3797s within a 30 second period in data mode is independent from the packet type (packet length). The calculation for a 30 second period is a follows: Dwell time = time slot length * hop rate / number of hopping channels *30s Example for a DH1 packet (with a maximum length of one time slot) Dwell time = 625 μs * 1600 1/s / 79 * 30s = 0.3797s (in a 30s period) For multislot packet the hopping is reduced according to the length of the packet. Example for a DH5 packet (with a maximum length of five time slots) Dwell time = 5 * 625 μs * 1600 * 1/5 *1/s / 79 * 30s = …
