Data Recovery from GPS???

[Peter Fanelli]

A quote from a post in another Australian aviation forum.

The last line made me smile :E


On 21 December 2007, an Evektor Sportstar, Recreational/ Light Sport
Aircraft registration 24-4148 was involved in a fatal accident 12 km SE
of Bindoon ALA. Recreational Aviation Australia (RA-Aus) staff commenced
an investigation into the occurrence. Three Global Positioning System
(GPS) units were recovered from the accident site.

On 9 April 2008, RA-Aus requested technical assistance from the
Australian Transport Safety Bureau (ATSB) to recover the data from the
GPS units. No analysis of the data by the ATSB was sought by RA-Aus. To
protect the information supplied by RA-Aus and the investigative work
undertaken to assist RA-Aus, the ATSB initiated an investigation under
the Transport Safety Investigation Act 2003.

Data was successfully recovered from all three GPS units in May 2008 by
ATSB Technical Analysis staff and subsequently provided to RA-Aus
investigators.

It appears that the ATSB were called in to recover data off three GPS
units which were carried on board.

What interests me is that they had three GPS units - why would you
carry this many.

The aircraft was on a mission with 2 pilots on board to pick up a Piper Super Cub from another field. Suspect that the *co-pilot* was carrying a GPS with him also and I guess it would be possible that the aircraft had 2 on board as standard equipment.

As for data recovery, *most* GPS units record movements and altitudes for a reasonable period even though the user may not be aware of this.

A gent recently in Melbourne was caught in his Toyota Hilux doing over 120kmh, but got off it because his el-cheapo handheld Magellan GPS on the dash kept records of his speed and he wasn't going over 100kmh at the time (verified by a scientific type government department).

There is an internet where GPS data can be uploaded and viewed in plan, altitude profile and groundspeed.
