DR + GPS
STARTER KIT REFERENCE MANUAL
Lassen DR + GPS Reference Manual 12
The Trimble® Lassen® DR+GPS combines dead reckoning (DR) with GPS to
produce accurate and instantaneous positions, even under the most difficult
conditions. For service providers tracking high-value or perishable cargo, Lassen
DR+GPS dramatically improves quality of service (QoS) and customer satisfaction
and retention, helping tracking service providers to maximize revenue opportunities.
Dead reckoning (DR) estimates position based on heading and distance traveled
since the last known position. The more accurate the speed, time and heading
inputs, the more accurate the dead reckoning. This is where GPS helps. GPS
continuously calibrates the gyro and speed sensors to produce optimal dead
reckoning.
Instantaneous and accurate positions in deep urban
canyons and dense forests.
Continuous position outputs in tunnels, parking
garages and on lower bridge decks.
Reliable positioning for tracking high-value assets and
for mapping RF field strength.
