HI, I am wondering if anyone ever tried the Pretec CompactGPS. I don't know about the software, but the hardware spec looks quite interesting and might be superior to other Compact Flash receivers: built-in Li-ion battery to cut down start up time, can be used in laptop with adaptor, altitude info..... Any thoughts? HOw is the Pharos receiver by the way?
Specification:
CompactFlash form factor, CFA Compliant
OEM product development is fully supported
Twelve parallel satellite tracking channels for fast acquisition and reacquisition
Support for true NMEA-0183 v2.2 data protocol
Enhanced algorithms provide superior navigation performance in urban canyon and foliage environments.
Maximum navigation accuracy achievable with the Standard Positioning Service (SPS)
Enhanced TIFF upon power-up when in a keep-alive power condition before start-up
Meets rigid shock and vibration requirements
Automatic altitude hold mode from three-dimensional to two-dimensional navigation
Automatic cold start acquisition process
Built-in Antenna
Power saving mode with trickle power
LED indication for navigation update
Data retention with Li-Ion battery inside
Reversed straight MMCX subminiature, snap-on, coaxial RF jack receptacle
