Early notice for a flight I'm hoping to do next Thursday.
It has a
single Pi tracker using LoRa on 434.500MHz, and my "mode 1"
(Implicit/EC 4:5/BW 20.8kHz/ SF6), sending telemetry and SSDV. Payload
ID is "ASTROPI". There will be no RTTY this time.
As well as
PITS and LoRa boards, the Pi has a "Sense HAT" as used by Tim Peake on
the ISS. Values from the sensors on that board will be logged locally
and included in the telemetry transmissions.
The signal will stop
every 30 seconds for a 5-second uplink slot. By no coincidence
whatsoever, the flight date is Tim Peake's birthday and I will be
inviting people to tweet suitable messages which will be relayed to the
payload via the LoRa uplink. Messages will then scroll on the Sense HAT
LED matrix and recorded on a video camera. in the absence of tweeted
messages, the matrix will display the altitude and temperature.
I'll post the twitter hashtag shortly before the flight.
