Omnidirectional bonus for miniature GPS antenna
Antenna specialist Sarantel has announced the PowerHelix GPS-P, a miniature GPS antenna which is omnidirectional and therefore tolerant of the orientation of the GPS receiver.
Novel GPS antenna picks up more satellites
The GeoHelix-H is a new-technology high-gain active antenna for portable GPS receivers which enables more satellites to be acquired than conventional patch devices.
Tests conducted by Sarantel have shown that when mounted in the foot-well of a production car, the SmartAntenna provided its first fix in under 15s from a warm start and tracked a minimum of six satellites during an urban test route.
In any vehicular tracking application this translates to near-instant results when a location is changed and continual tracking accuracy while on the move.
Barrie Foley CEO said: "The current take-up of personal navigation products is creating an anticipation of good in-vehicle performance from both commercial and consumer focussed GPS products.
Until now, good in-vehicle performance was simply not possible without an external GPS antenna and users were not impressed".
Sarantel hopes the test results of the new SmartAntenna will be attractive to manufacturers wanting to add GPS functionality to portable equipment and to specifiers of automotive installations, including covert security and asset tracking.
In the exhaustive tests devised to test the SmartAntenna's ability to operate within the vehicle, carrier to noise ratio exceeded 40dB most of the time demonstrating the devices ability to reject non-GPS RF signals from outside and inside the vehicle.
SmartAntenna F02 combines Sarantel's omnidirectional GPS antenna with Fastrax's popular ultra-low-power Trax02/4 GPS receiver chipset.
The antenna's innovative GeoHelix design offers exceptionally high levels of immunity to RF interference thereby simplifying the integration process.
It is particularly small at 32 x 32 x 10.8mm, weighs under 30g, and consumes just 100mW at 2.7V in continuous operation, making it ideal for portable applications and for vehicle, personal, and mobile asset tracking where battery power is used.
