SP9UOB

Post by sp9uob » Mon Mar 02, 2020 6:17 pm

PIC-o-Tracker rev7
PIC18F26k22, SI4460, uBlox GPS
Ready-to-flight weight 4.3 grams
Telemetry (every minute, but it depends how much power do we have) Contestia 8/250, Morse (Callsign, Locator, alitiude), frequency agile APRS AFSK 1200 baud and GMFSK 9600baud.

Log data is stored onboard, and then transmitted down using APRS. So I can recover tracker path even, there are no receivers in range.

Live flight data:
https://tracker.habhub.org/#!mt=roadmap ... SP9UOB-P37

SP9UOB is import from APRS, and SP9UOB-P37 is from contestia mode.

For now the last received packet is at 2020-03-02 17:15:35 Local time

Pico-37 is still alive. It woke up today over Ukraine.
Unfortunetly, there is poor APRS coverage, so Im expecting 2-3 days of silence.

No news for today. It is (as expected) over territory without APRS coverage.

No news. It should be near Japan - but no signs of life.
It hit the tree during the launch, so envelope could be damaged.

My Pico just showed up over Alaska :-)
It should download track logs when it will be over good APRS network :-)

That is amazing! Fingers crossed.

Why is there a one hour difference between SP9UOB and -P37?

Thanks.

SP9UOB-P37 is recovered from APRS and track logs. So there might be difference.

It survived both oceans!
It is over The bay of Biscay and heading directly to UK. Because UK is forbidding airborne ham radio activity, TX will be switched to 434.550 MHz with reduced power (contestia/cw only)
