ANSR-17 Flight Summary

Launch 20 Mar 2004, 1559 UTC, (8:59 AM MST)

Payloads
Payload Computer, S-Band Video link, Micro Beacon II

Flight Notes
Unusual flight path and double temperature inversion caused by winter-time weather conditions.  First flight of S-Band video link.



Flight Data


Data and statistics recovered from Flight Data Recorder:

3.2 statue miles from the launch site on a heading of 312 ° true.  Shortest distance from lift off to landing within Arizona.  A flight in Colorado at GPSL 2003 was shorter at 2.1 statue miles.

Fight time 3:32:46, landed 1931 UTC, (12:31 PM MST)

Departed at 1437', landed at 1330'.

Peak altitude 104993'.

Average ascent rate 630'/minute.  Average descent rate 2148'/minute.  At touch down 950'/minute.

Lowest internal payload computer temperature 23.2° F, average 48.8° F.

Lowest external temperature -73.3° F during descent, average -4.7° F.

GPS maintained 100% 3D lock during flight  Average PDOP 1.50.  Average of 8.6 tracked satellites.

Average bus voltage 8.27 volts.

Payload Performance


The following is the performance of each payload package.

Micro Beacon II Operation nominal.  Excellent work by Louis, W7LWM, to improve mechanical soundness of the package.

S-Band Video Link Operation nominal.  This was the first flight of the the S-Band video link.  Results were very positive with great video images, including the burst, viewed in high resolution color.  Need to create antenna tracking system.  Manually holding and pointing the antenna is fatiguing.

Payload Computer Operation nominal.

ANSR-17 APRS Data

APRS data as received at IRLP node location.
ANSR-17 Flight Path Topographical Map.  Winter weather pattern create an interesting and variable flight path.  From the launch location, the flight tracks to the west, north-west, and then to the north.  From there, the flight path wonders in 10 mile square pattern.
ANSR-17 Landing Prediction Landing Prediction Map.  This map shows the first prediction packet at burst vs. the actual touch zone location.  There is only a 1.2 mile difference.  The landing prediction is based on the wind data collected during the ascent phase of the flight.  The error in landing location is primarily caused by differences in winds between the ascent and descent phases of the flight.
