Smaller, lighter and
longer. These are requirements for tracking devices of today. What
sound like contradiction can be explained easily: Smaller dimensions,
lower weight and longer battery running time.
For such requirements Round Solutions offers the ORG4472 GPS
module based on the brand new SiRF IV chipset. Available is a fully
automotive and industrial compliant module – with only 7 x 7x 1.4 mm
the smallest GPS module of the world.
"This new SiRFstar IV chipset of the module provides higher sensitivity
and consumes less power than previous GPS systems", explains Olaf
Schaefer, Technical Director at Round Solutions. "This extends battery
life especially for small handhold devices because now passive GPS
antennas can be used without losing performance", he says.
The ORG4472 is mounted by SMT (Surface Mount Technology).
There are no cost s for RF connectors or cable and no manual work is
need in production. Its integrated interface for accelerometers,
gyrometers or other sensors makes "Dead Reckoning" easy. Using
"Dead Reckoning" tracking can be continued even without sight to
satellites, for example in tunnels.
Free access to the test server www.track4less.com and
www.track4free.com facilitates the use of geodata.
"With th ese servers working proof of concepts can be realised within
days", explains Schaefer with reference to features of public-domain
software such as OpenStreetMaps and Openlayers.
