GPS Device Connector

Connect to a GPS device and easily read and ingest its location-based information with IOTech’s highly reliable GPS device connector.

Protocol Description

GPS (Global Positioning System) is a satellite-based navigation platform operated by the United States government. It provides location, velocity and time synchronization data for air, sea and land travel. GPS does not require the user to transmit any data and operates independently of any cell or network coverage. GPS is free-to-use and has become the de-facto tracking/positioning service. It is used by over 1 billion devices worldwide.

Edge IoT use cases for GPS include asset monitoring, transportation, fleet management and healthcare. Information provided usually includes time, date, track, climb, altitude, speed, latitude and longitude.

A device with a GPS receiver runs a local GPS module that accesses the satellite-based information. Edge Gateways and Servers usually operate a GPS daemon to manage the GPS module. Most GPS modules utilize the National Marine Electronics Association (NMEA) specification that defines a standard format for GPS data.

GPS Connector Specification

IOTech’s GPS device connector supports the collection of key positional information provided by GPS devices

The GPS device connector requires connection to a GPS daemon and implements the following key features:

• Connection to either a local or remote GPS daemon (gpsd)

• Support for connecting to the GPS daemon in both polling and non-polling modes

• Pre-configured support for reading the following data from the GPS daemon : time, date, degrees from true north, speed of climb, vertical positioning, speed of travel, latitude and longitude

• Support for String and Float64 data relating to the above data
