Request for Access to SatNOGS S-Band (2430 MHz) Ground Station for Satellite Data Reception

Satellites & Observations Launches

Dear SatNOGS Team,

I hope this message finds you well.
I am writing to request access to a SatNOGS ground station equipped with an S-band receiver (centered around 2430 MHz) to support the reception of telemetry and payload data from our satellite.

Our mission aims to send data using our S band transmitter in KOSAR 1.5 .
We would like to schedule observations through the SatNOGS network to receive and decode the satellite’s downlink during its operational passes.

Below are the key details of our mission and signal:

  • Satellite name: KOSAR 1.5 (2SEE1)
  • NORAD ID (if available): …
  • Downlink frequency: 2430 MHz
  • Modulation: LoRa
  • Symbol rate / data rate: ~120kbps
  • Sat Polarization: RHCP
  • Expected Antenna Gain : 30dBi

We kindly request access to a suitable SatNOGS S-band ground station for a series of test passes and operational downlinks. If any additional configuration or licensing details are required, we will be happy to provide them.

Please let us know the process for approval and any technical information you may need from our side.

Thank you for your time and support in enabling this collaboration.

Best regards,
Pouria Zarei

Dear Pouria,

2430 MHz is crowded over here with Wifi signals. My bet would be this frequency is not the best choice to look and find S-band stations. Most use a passband filter which cuts quite strongly at 2340 MHz to prevent the Wifi, bluetooth and more to come in.

Greetings!

Could you please list all of the LoRa parameters that will be used?

I am referring to:

BW
SF
CR
Preamble Length
Sync Word
LDRO on/off
CRC on/off
Inverted yes/no

Thank you!

Two notes:

  1. For making available your satellite and its transmitters in SatNOGS DB, you can follow these guides on how to add suggestions: Satellite Suggestions - SatNOGS Wiki and Transmitter Suggestions - SatNOGS Wiki

  2. SatNOGS Network can not demodulate LoRa transmissions due to its proprietary nature, you can find more details in LoRa protocol in space, however adding the transmitter in SatNOGS it will be useful for 3rd party observers that use SatNOGS DB for finding frequencies.
