Photos of the payload during construction and testing
Like the former flights, this one also uses a special U3S firmware version on an Arduino Nano board.
The map below is updated automatically with the latest received position during the balloon's flight. During the balloon's night time the battery is quickly depleted, so from just after sunset there are no more reports until daylight.
This is the telemetry schedule provided by Dave VE3KCL
See the S-4 page for more details of the telemetry protocol. The transmission schedule for the flight is based on a 12 minute transmission cycle, commencing on the hour and repeating every 12 minutes, i.e. at 00, 12, 24, 36 and 48 minutes past each hour. A distilled version of the schedule is:
|00||30m||10,140,460||JT9||Callsign VE3KCL + 6-character Maidenhead locator|
|01||30m||10,140,480||JT9||Altitude + groundspeed|
|02||20m||14,097,155||WSPR||Standard WSPR message with callsign VE3OCL|
|04||20m||14,097,155||WSPR||WSPR telemetry message on channel 3|
|06||30m||10,140,255||WSPR||Standard WSPR message with callsign VE3OCL|
|08||30m||10,140,255||WSPR||WSPR telemetry message on channel 3|
|10||90 seconds of GPS calibration|
