2A8AP-LS300LS300 Sensor and Relay

LS300 Sensor and Relay Wireless satellite terminal with integrated multi-band circularly polarized antenna system FEATURES • 862-870 MHz or 902-928 MHz RHCP antenna • MSS S-band RHCP antenna • GNSS RHCP antenna • 84 x 84 x 20 (mm) without casing • 94 x 94 x 45 (mm) with casing LS300 SENSOR AND RELAY https://lacuna.space DESCRIPTION The LS300 Sensor and Relay has been designed for direct communication with the Lacuna satellite network. The terminal is battery powered and is based around a dual-core ARM M4/M0+ processor. The terminal contains a number of sensors, a GNSS receiver and has an integrated Right Hand Circularly Polarized (RHCP) satellite antenna, providing a 110° wide beam. The terminal should be used outdoors and is contained in a protective enclosure. The terminal communicates with the satellite network in both SRD/ISM- Band as well as in the S-Band. It can be ordered in two different SRD/ ISM frequency band configurations: 862-870 MHz or 902-928 MHz. The S-Band antenna is tuned to 1980-2200 MHz (1980-2010 MHz uplink, 2170-2200 MHz downlink) for both configurations. APPLICATIONS The primary applications of the terminal are direct communication of (internal) sensor data to the satellite network and relay of data received from third party LoRaWAN ® compatible sensors or devices. As such the device is ideally suited for getting acquainted with the services offered by the Lacuna satellite network. The device may also be used as a reference design for third parties wishing to develop their custom designs.

With the LS300 Sensor and Relay terminal all these components are integrated onto a single printed circuit board resulting in a much smaller and power efficient device. All components listed in the table below are surface-mounted, integrated chips that cannot be removed or replaced without damage to the electronics board. The components cannot be used as stand-alone modules.
