Fairview St. Suite 101 Chandler, Arizona 85224 April 2013 - 2 - Space Data Corporation Confidential and proprietary information 1.0 Introduction The Space Data Corporation SkySite network is designed to provide narrowband wireless paging, Machine-to-Machine (M2M), and Push-to-Talk voices services to remote areas that are not practically serviced by traditional terrestrial communication towers. This narrowband wireless coverage is accomplished by mounting the functional equivalent of a communications tower on a high altitude weather balloon thereby overcoming service limitations. The SkySite Network consists of 5 subsystems listed below. 1. SkySite Platform (either SkySite 900 Mark 1 or SkySite 900 Mark 2 models) 2. Launch Facilities 3. Ground Station 4. Network Control Center. 5. SkySite Control Center Figure 1.1: The SkySite Network This document is a summary of the procedures used to deploy and operate the SkySite network. All equipment shown is manufactured, operated and serviced by Space Data Corporation and is therefore meant for internal use only. - 3 - Space Data Corporation Confidential and proprietary information 2.0 Pre-Launch Control Center operations are managed through the use of several Space Data Corp. proprietary software applications. These client applications run from EPS (Engineering Programming Software) server: GST (Ground Station). The GST maintains the communication link from the ground to the SkySite. The GST also monitors and controls ground station functions such as antenna auto-tracking, Receive signal strength, TX and RX power levels and frequency correction. SkySite client. Monitors SkySite performance such as TX and RX power levels, GPS position, battery current and voltage, and AH consumed. Vent ballast controls and accumulated values release command. Mapping client. This application utilizes the GPS coordinates sent from the SkySite and superimposes it on mapping software. Terrain and population density are easily determined from this screen and is used to plan recovery of the payload. The mapping client also has predictive capability. Using wind speed and direction information obtained on ascent, the software can predict where a SkySite will land if release at that moment from the balloon and descends using its parachute. 2.1 Pre-Flight Client Preparation Start all GST (Ground Station Transceiver) and SKS (SkySite) clients. Both software applications should connect to the EPS (Engineering Programming Software) server. During operation each client should appear as shown in Figures 2.1 and 2.2 below. Figure 2.1 – GST Client Screen - 4 - Space Data Corporation Confidential and proprietary information Figure 2.2 – SKS Client Screen Determine the type of antenna used by the Ground station in operation. There are only two types of antennas used for the Ground Station: 1. Omi-directional antenna (Max. Gain of 3dBi) 2. Yagi antenna (Max. Gain of 10dBi) Determine the type of antenna used by the SkySite (SKS900 or SKS900MK2). There are only two types of antennas used for the SkySite: 1. Low Gain Antenna (Antenna 1) (Max. Gain of 3dBi) 2. High Gain Co-Linear Array Antenna (Antenna 2) (Max. Gain of 9.22 dBi) Caution: In order to comply with FCC Part 24 and RF (Radio Frequency) exposure limits of this product the maximum GST ERP (Effective Radiated Power) must not exceed 7 Watts into a dipole antenna a gain of 2.15 dbi (40.6 dBm). When Antenna 2 is used with the SkySite, the transmit power at 901 MHz must not exceed 31 dBm. This power level when combined with the gain of Antenna 2 is below the 7 Watt ERP limit of FCC Part 24 for 901 MHz transmitters. - 5 - Space Data Corporation Confidential and proprietary information Transmit power levels are shown in the bottom left corner of the GST client in the “TX GLP HPA STATUS” box. This value does not include the directional gain of the antenna. Therefore the maximum permissible power levels into the antenna as are as follows: 1. Using the Omni-directional antenna the maximum power is 35dBm. 2. Using the high gain Yagi antenna the maximum power is 28dBm. Transmit power levels are shown in the bottom left corner of the SkySite client in the “TX GLP HPA STATUS” box. This value does not include the directional gain of the antenna. Therefore the maximum permissible power levels into the antenna as are as follows: 3. Using Antenna 1 (low gain) the maximum power is 35dBm. 4. Using Antenna 2 (co-linear dipole) the maximum power is 31dBm.  Start all GST and SKS clients. Ensure that GST clients connect to EPS server. On GST Client open the GLP RSSI and GPS screens  On the SKS Client open the following screens: GPS. GLP RSSI. Altitude vs. heading graphs. Altitude vs. Horizontal speed. Vertical speed graph.  Check Antenna Control: Disable tracking Ensure client is in “remote tracking” mode. For each GST client slew antenna in azimuth and elevation. Point antenna toward launch site at 0 degrees elevation.  Start GPS client on mapping PC and ensure it connects to EPS server. The GPS client started must correspond to the GST that will be used to control the payload. - 6 - Space Data Corporation Confidential and proprietary information Figure 2.3 – Mapping Client Screen  Start predictor software on mapping PC  Start Delorme payload and predictor programs on mapping PC.  Start Delorme payload and predictor programs on mapping PC. The mapping client should look like Figure 2.3 as shown above. 3.0 Balloon Fill Steps 3.1 Initial Preparation  Arrive 1 hours before scheduled launch  Obtain pre-flight checklist  Turn on handheld radio for communication with local airport traffic (if applicable)  Verify channel and that comms are operating - 7 - Sp…
