Ocellus S100 high sensitivity GPS tracking from Qinetiq
May 23, 2007 gps navigation, tracking
Qinetiq, a government contractor, has announced the arrival of Ocellus S100, a new tracking device that utilizes the super sensitive Q20 GPS receiver. The Q20 has impressive specs, and if they are true it really does provide the most sensitive reception at -189dBW for tracking and -185dBW for acquisition.
The central component of Ocellus is QinetiQ’s Q20 high sensitivity GPS receiver, an award winning technology, that provides reliable position data in areas that conventional GPS cannot. This allows Ocellus to work inside a vehicle, in the glove box, under seats or in the boot of a hatchback. A unit can even be fitted to the underside of a vehicle where it is able to use GPS signals reflected from the road surface.
Ocellus S100 also contains an activity sensor that detects motion, allowing the unit to update its position if it has been moved. This sensor permits the selection of tracking profiles that, for instance, request a position report only once a day unless motion has been detected, in which case the unit “wakes up” and reports its position. Alternatively, if Ocellus knows that it has not moved since its last position report, it will not report the same position again, thus conserving power and saving money.

According to http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=23286, their chip is actually less sensitive than SiRFStarIII, they just use dBW instead of dBm for the measurement. SiRFStarIII is -159dBm (-189dBW) and QinetiQ Q20 is -155dBm (-185dBW).

Razvan is right, they just don’t use the usual unit.

I’ve got a unit and its incredible, I’ve tracked cars, parcels, people and in all weathers. Unit was stuffed in a parcel at back of truck and still worked perfectly, sending a fix every 60 seconds.
I even sent it in a parcel via parcel post to watch its progress…never lost it once and it must have been inside a few distribution centres on the way

We have been using this unit in the USA at http://www.globaltrackingtech.com and performance is good.
