GPS-SAPPHIRE
Global Positioning System receiver

This Starter Pack contains:

l Sapphire GPS receiver

l LP2957 +5V voltage regulator

l 2.2uF/16V tantalum capacitor

l 100k resistor

l Circuit diagram (not shown)

This GPS receiver is housed in a hemisphere and the unit has overall dimensions 62 x 50 x 27mm. The base is strongly magnetic so that the receiver can be used on the roof of a vehicle.

The connecting wire is 1.3m long and has four flying wire connections for transmit, receive, +5V and ground. Current consumption is 180mA typical. A circuit shows how to connect together the voltage regulator, GPS receiver and the TDS2020F. Included is the ability for the computer to turn off the GPS receiver to save power.

The unit outputs NMEA GPS data at 4800 baud suitable for processing by library routines in a TDS2020F embedded computer.
