Pupils at Wirral Grammar School for Girls are planning to launch a High Altitude Balloon equipped with 434 MHz telemetry and Slow Scan Digital Video (SSDV) transmitters.
The launch is planned for Wednesday, July 16 at around 11:00 BST from Middletown Hill near Welshpool, weather permitting. The balloon will be a 1200g Hwoyee with Helium and the transmitter details are:
Frequency: 434.300 MHz
Mode: RTTY 50,7n2 470 Hz shift
Frequency: 434.350 MHz
Mode: RTTY 300,8n2 610 Hz shift SSDV + telemetry
The balloon will carry a Raspberry Pi A with RFM22B based daughterboard. The radio coverage area could extend up to a radius of 700 km which would make it receivable throughout the British Isles.
