Balloon Experiments – 9V1UP-11

Saturday 4 Sep 2021 23:00H / 15:00Z. APRS on 144.390 BEACON only.

Join the fun hunting for the APRS signals after launch. The balloon is estimated to be in the air for a few hours. Signals are likely to be received in the region: Singapore, Johor, and Riau. For the past few months, a team of Singapore hams have worked on a project to launch a weather balloon carrying amateur radio. The flight system consists of a 600g weather balloon filled with Helium (industrial grade) and the payload is assembled from a LightAPRS tracker. Approval of flight involved “no objection” from CAAS, RSAF and IMDA, and Saturday’s flight requires release clearance from RSAF duty controller. For launch, two teams will be deployed in the western side of Singapore. The launch team will attend to the lift off while the remote monitoring team will receive and iGate the APRS signals.

Updates: Ham Radio SG on Facebook

The project team is busy preparing for the launch and may not have time to answer questions that you may have. A presentation will share various aspects of the project at the next SARTS meeting. Come this Saturday, share in comments when you receive 9V1UP-11, stating your QTH and telemetry.
