Beacons are encapsulated in AX.25 + HDLC frames, with G3RUH scrambling and NRZI encoding. The following image shows the overall beacon format: gr-ax100 GNUradio decoder for transceivers from GomSpace.
The AX100 module will ship with firmware pre-installed. Uploading new firmware will void the factory checkout. 4 © 2019 GomSpace A/S NanoCom AX100 Datasheet Long-range software configurable VHF/UHF transceiver The AX100 integrates in a Cubesat using the NanoDock auxiliary board that can also host other miniaturised GomSpace avionics modules, e.g. the NanoMind A3200 On- Board Computer. Flexible transceiver module for UHF and VHF bands with multiple databuses (I2C and CAN) allowing fully redundant architectures. Network centric Dual GomSpace NanoCom AX100 Radio modules for polarization diversity Same transceiver in both ends simplifies hardware development as well as software development 19” rack-cabinet with external 12 V supply Also available in a lab version for testing: NanoCom GS100L that only contains one AX100 with one antenna connector, and an USB to PC GOMspace AX100 deframer¶ The GOMspace AX100 deframer implements two different protocols used by the popular GOMspace NanoCom AX100 transceiver. These two protocols are: ASM+Golay.

This uses a header encoded with a Golay(24,12) code that indicates the packet length.

The data rate will be 9.6 kilobits per second (kbps). Because RANGE is a two-satellite mission, communication requirements for RANGE include simultaneous contact with two satellites during AX100: GomSpace: 140-144; 399-403: GFSK/GMSK: SRS-3: Satlab: 2025-2110; 2200-2290: GMSK: Li-1: AstroDev: 137-144; 399-403: FSK/GMSK: The setup process.

AX100 modu-lates and encodes the telemetry and transmits the information on a carrier signal of around 400 MHz. The ground station needs to detect this signal, convert it to data (demodulate it),

GOMX-3 uses the next generation of CubeSat OBC (NanoMind A3200) and UHF radio (NanoCom AX100). On the contrary, TY-2 uses an AX100 transceiver in the ASM+Golay mode. It can only be decoded with gr-satellites and one of the UZ7HO’s soundmodems, as far as I know (as well as with the GOMspace groundstation GS100 hardware or with another AX100 transceiver).

Nevertheless, SatNOGS DB makes a distinction between FSK, GFSK, MSK and GMSK. Introduction¶. gr-satellites is a GNU Radio out-of-tree module encompassing a collection of telemetry decoders that supports many different Amateur satellites.This open-source project started in 2015 with the goal of providing telemetry decoders for all the satellites that transmit on the Amateur radio bands..
Par Julien NICOLAS 07/03/2020 I'm working on a CubeSat comms team to implement a power splitter/combiner in order to connect our GOMspace AX100 UHF radio and our EnduroSat UHF radio to the same (crossed dipole) antenna. The ultimate goal would be to have both radios on and functioning, both capable of receiving, and either one able to transmit without having to worry about the other radio.
