====== Nova 14 ====== ===== Launch Card ===== No launch card was filled in for this flight. | Date | 21/8/09 | | Description | First flight of BadgerCub and first uplink test. Payload consisted of GU box containing BadgerCub. | | Launch Time | 14:50 GMT | | WX | 3/8ths cloud cover, clear, windy on the ground | | Balloon Size | Old ropey 250g | | Target Neck Lift | | | Target Asc. Rate | | | Neck Load | | | Neck Lift | | | Parachute Details | 50cm nylon parasheet | | Estimated Burst Altitude | 22km (old balloon so rough guess) | | Cutdown Criteria | N/A | | Telemetry Details | CC1111 radio transceiver, 10mW 50baud RTTY on 454.525MHz. Uplink 50baud OOK | | Notes from Launch Card | | ===== Flight Vitals ===== | Maximum Altitude | 26670m | | Ascent Rate | | | Sea Level Descent Rate | | | Telemetry Log | {{:badgercub_uplink_flight_log.txt|Nova 14 Telemetry Log}} | | KML File | {{:badgercub_uplink_test.kml|Flight Path KML}} | | Photos | No camera flown, [[http://www.flickr.com/photos/cuspaceflight/sets/72157622162980562/|Photos]] from the ground | | Videos | | ===== Notes and Details ===== First flight of the [[BadgerCub]] and first ever uplink to a payload. Uplink to [[CC1111]] tested. Sacrificial flight to test uplink range. Strong winds carried the payload out to the middle of the channel and uplink was successful to a range of approx. 190km. More details on the uplink method are on the [[CC1111]] page. We made a scatter plot of successful string uploads plotting range from the ground station against transmit power used. The payload antenna was a 1/4 wave whip with 4 radial grounding elements. The ground station had a 7-element yagi and an IC-7000 with maximum transmit power 35W. A couple of times during the flight we attempted to see the power minimum for successful uplink and these can be seen as the vertical arrangements of points in the plot. {{badgercub_range_graph.png?500}}
