GRIFEX active and decoded

Posted on by

With the help of the recorded IQ file that can be downloaded at the following location, I was able to decode and send a couple of kiss packets to the GRIFEX telemetry server. Below you can see the data decoded by the MXL Ground Station Client.

UZ7HO-kiss-serverI used the UZ7HO G3RUH 1.7 beta sound modem software and enabled the Kiss server on port 9100. After that I configure the config.props file that is part of the MXL Ground Station Client software to use the kiss server port. Below the config.props I used.

Don’t use the tcp to serial option that comes with the GS client software. There is a direct connection between the GS client and UZ7HO via in my example port 9100.

Good luck decoding GRIFEX with this setup.

AESP-14 Deployment

Posted on by

AESP-14-CubesatFirst Cubesat Developed in Brazil.

PY2SDR has confirmed the deployment of AESP-14 from the International Space Station at 14:30 UTC on Thursday, February 5.

The AESP-14 team would like to ask the help of the AMSAT community to forward any received telemetry frames back to the team. For this, please save the AX.25 frames in KISS format and forward the file to aesp14 (at) ita.br. Telemetry format can be found at this location: AESP14-Telemetry Format.

AESP-14 CubeSat
Frequency: 437.600 MHz 9k6 AX25

After launch we can use the TLE data from ISS.
