NanoAvionics UHF Digital SatCOM utilizes a half-duplex architecture with a high-performance low power consumption transceiver which is controlled by a dedicated Cortex – M4 MCU. The radio uses the ultra-high frequency band (UHF) that is programmable in 430 to 440 MHz range. The receiver has an excellent sensitivity of -120 dBm at 9600 baud rate and the transmitter supports high throughput data communication in narrowband channels with GDSK, FSK (including G3RUH), MSK and OOK modulations.
A bandpass filter can be selected depending on customer-specific frequency (e.g. 435 – 438 MHz for radio amateur satellite frequency band). Transceiver can operate in transparent mode for customer-specific protocol support or in AX.25 packet mode. When used with NanoAvionics 3C2 flight computer, 2 UART and 4 I/O pins of the radio are used to control the upload of the firmware for ADCS and OBC subsystems in orbit.
