Richard, do you want pre-packaged working units? Or are you willing to adapt a GPS chip set to your project and interface it to your own host CPU? At one time these guys www.snaptrack.com were able to provide the ship sets and required code that needed to run on a host CPU: SnapCoreTM: The SnapCoreTM Multi-mode GPS (MMGPS) solution is an easy to integrate, high performance means of implementing SnapTrack's Wireless Assisted GPSTM (WAG) wireless location system. SnapCore enables the tight integration of WAG into any wireless communication device (phone, PDA, pager, modem, etc.) by embedding logic gates into components that already exist in the device, or by implementing the gates on a small IC placed along side existing components. It also leverages the power of SnapTrack's proven algorithms for multi-path mitigation and sensitivity enhancement. These leading edge algorithms, combined with the high level of integration, provide unmatched GPS acquisition speed and sensitivity, while minimizing cost, space and power. There is also: http://www.sirf.com/products.html Sirf has respun its SirfStarIIe chip set in an 0.18-micron process to create the SirfStar-IIe/LP. It is also offering a simplified version of the chip set that off-loads navigation processing to a host CPU and another version that makes its GPS signal-acquisition technology available as a block that can be integrated with a host processor.

(This pricing is for the OnCOre Mototola GPS module from http://www.synergy-gps.com/Products_New.html This still puts our current project at risk of never getting done as we need a steady supply at $50 for the module and antenna! So the search continues for a cheaper alternative...... Richard. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
