Lost Payload Recovery

Below are several spreadsheets. Here are the first few records from the "sep_payload_10000.csv" spreadsheet.

What you are seeing here is the beginning of an analysis of where a payload would land if it separated from the main payload line at the time and altitude indicated. So, approximately 30 seconds after the launch of EOSS-103 at 13:29:54 UTC, the payload would have landed at:

• 40.47277 N Latitude
• -104.962 W Longitude

Which is

• 0.0658 statute miles from take off position
• 161.4176 degrees true from that spot.

Predictions are given for each and every packet heard from the balloon and the position reported is the predicted landing location.

The file names below represent the descent speed in FPM at sea level. If you have a particular descent rate you wish to have predictions run for, send it along to me (webmaster) and I'll run the prediction and post the results here for you.

• sep_payload_2000.csv
• sep_payload_3000.csv
• sep_payload_4000.csv
• sep_payload_5000.csv
• sep_payload_10000.csv

Assuming a separation at burst, here are three positions of interest, one each, from the 4, 5 and 10K descent rate predictions. But, you may have telemetry that points you in a totally different direction.
