Information for Radio Amateurs

This page is dedicated to the amateur radio community and lists information related to our SONATE-2  mission. Activation of our amateur radio payloads (SSTV, APRS Digipeater) will usually be announced on our X account @JMUSpace.

Please contact sonate-2@uni-wuerzburg.de for any questions regarding SONATE-2 amateur radio operations.

Two Line Elements (TLE)

The NORAD-ID of SONATE-2 is 59112 and its international designator is 2024-043Q. Current TLE information can be found on the CelesTrak website.

Telemetry Downlink

During passes over our ground stations in Germany the telemetry downlink of SONATE-2 will be activated.

  • Frequency: 437.025 MHz
  • Modulation: 9k6 G3RUH GMSK (F1D)
  • Protocol: AX.25

The protocol format used for encoding the telemetry frames can be found >>here<<.
Recorded AX.25 frames can be forwarded to sonate-2@uni-wuerzburg.de

CW Beacon

SONATE-2's CW Beacon is only sporadically used mainly during LEOP for launch object identification. If activated, a beacon with the callsign of the satellite DP0SNX is transmitted at regular intervals as CW Morse code.

  • Frequency: 145.840 MHz
  • Modulation: Morse code CW (A1A)
  • Interval: 30 sec

APRS Digipeater

The APRS digipeater on SONATE-2 operates in half-duplex operation. The digipeater is only active when published below. When activated, it will transmit a greeting message every 2 minutes. Make sure to include SONATE-2's callsign DP0SNX in the APRS route.

  • Frequency: 145.825 MHz Up/Down
  • Modulation: 1k2 AFSK (F2D)
  • Protocol: AX.25
  • TX Power: 500mW

 

Planned Activation Schedule [Last Update: 30/09/2024]

The activation of the APRS digipeater on SONATE-2 is planned at the following times. Due to unforeseen circumstances, the planned times can also change at short notice. The begin of an APRS event is usually announced on our X account @JMUSpace.
