National Marine Electronics Association (NMEA)
National Marine Electronics Association (NMEA) is a protocol by which marine instruments and most GPS receivers can communicate with each other. NMEA defines the format of many different GPS message (sentence) types, which are intended for use by navigational equipment.
Example of a tracking application using NMEA:
•Microsoft Streets and Trips

Trimble ASCII Interface Protocol (TAIP)
Trimble ASCII Interface Protocol (TAIP) is a digital communi‐ cation interface based on printable ASCII characters over a serial data link. TAIP was designed specifically for vehicle tracking applications but has become common in a number of other applications, such as data terminals and portable computers, because of its ease of use.
Example of a tracking application using TAIP:
•DeLorme Street Atlas USA
Tip: For more information on TAIP message formats, refer to the
Appendix and to the Sierra Wireless MP 3G Modem TAIP Reference.
Datum
The GPS datum is the method of ascertaining the position of the GPS device using a specific reference point location. The datum used can influence the accuracy of the GPS positioning.
In addition to different reporting protocols, the PinPoint‐E supports the most widely used GPS datum:
•WGS84
