development of GPS software along with recommendation of the commecially available GPS device or suggest a device manufacturer

1. A GPS device capable of recording the distance travelled, speed and time elapsed since the begining of journey. 2. The data should preferably be logged every second or every meter. 3. In case the frequency of data logging is much longer, please provide approximate idea of the data logging interval. 4. It should be possible for the user to pre upload short instructions to driver like "stop" or "Brake" etc based on distance travelled and current speed. 5. The GPS device shall display the short instructions based on the pre-loaded information 6. In case the first stage turns out to be succesful, in the second stage following is planned: a. The device shall have an embedded software (which can be loaded to the device) wherein based on certain constants which entered through a MMI, the device shall carry out calculations using the software routine and determine the braking position or stopping position. The software for this purpose will be supplied by us or can be translated in the language required by you for which the flow diagram shall be provided by us. As of now, please quote for the first stage only with an indicative quote for the second stage. Regards,
