Update #1 8 Sep 2015

After being tossed around for a few hours by a rough weather front that caused rapid altitude changes of the payload in the Southern Ocean, PS-52 went down on Monday night, 4000km from the nearest tracking station ZL1RS in NZ.

Pebble Watch Apps for Picospace balloon tracking

I have written a little App for the Pebble Watch to assist with tracking of PICOSPACE balloons, starting with PS-30.

The watch displays the time from last telemetry, lat, long, altitude, speed, battery voltage and solar voltage.

The data is polled from picospace.net (via the phone) every two minutes. You will need internet connectivity from your phone (3G or Wifi).

If new telemetry is received after 30 minutes from last telemetry the watch will also vibrates.

The screen shot show PS-30 was heard from 7 hours 14 minutes ago, at 9697m, and speed of 216kmph.

PS-25 and PS-26 HF PICO balloons

PS-25 and PS-26 PICO balloons were released on Sat 22 Nov 2014, testing out multiple balloon tracking with JT9 and WSPR.

Solar powered 10mW TX HF payloads transmitting JT9 and WSPR with frequency offset of 400Hz for JT9 and 100Hz for WSPR, they could be tracked simultaneously with the modified WSJTX software.

Tracked on SNUS as PS-25 and PS-26.
Callsign on JT9 is VK3YT, and callsigns on WSPR are VK3YT and VK3ANH

TX time and frequency schedule:

0 30m // Mandatory JT9 and WSPR, two per hour
6 30m // Optional JT9 – bat full
10 20m // Optional JT9 and WSPR – batt low
16 20m // Optional JT9 – bat full
20 30m // Optional JT9 and WSPR – batt low
26 30m // Optional JT9 – bat full
30 20m // Mandatory JT9 and WSPR, two per hour
36 20m // Optional JT9 – bat full
40 30m // optional JT9 and WSPR – batt low
46 30m // Optional JT9 – bat full
50 20m // Optional JT9 and WSPR – batt low
