Location Tracking

Global Navigation Satellite System (GNSS) infrastructure allows the NTC-400 Series Router to determine its position, velocity,
and time by processing signals received from satellites orbiting Earth. GNSS can access a variety of satellite systems and
Satellite-Based Augmentation Systems (SBAS). SBAS is used to improve positioning accuracy.

Position applications are widely-used by a variety of industrial applications, including Location-Based Services (LBS),
Automatic Vehicle Location (AVL), Fleet Management, or assets tracking. However, in most cases, GNSS is a one-way
communication. That means GNSS-compatible devices can only locate their location by receiving a GNSS signal, but they
can't forward their location data to any other identity through the GNSS system. Because of this limitation of the GNSS
system, devices usually need to equip other technology to transmit their location data to back-end servers for tracking or
further analysis. Furthermore, as the position applications are more applied on moving objects, a kind of wireless technology
would be more suitable to be adopted to transmit location data. Nowadays, thanks to the popularity and wide coverage of
cellular technology (GSM, 3G, 4G/LTE), transmitting location data to a remote centre in real time is no longer a hurdle. In
addition, the data format of the location data is NMEA 0183 compatible, so the back-end server will be able to interpret the
collected location data.
