What does a tracking device consist of?
GPS tracking devices consist of a battery or electrical source, some have both, the ability to transmit over a cellular network, and a built in antenna. GPS tracking devices come in many sizes and usually are hidden so they remain undetected.
How many types of tracking are there?
There are basically three types available: plug in, hardwired and battery operated. Typically, these units take the information they gather and use a cellular connection to share it.
What are the frequencies used by the GPS system?
All GPS satellites broadcast on at least two carrier frequencies: L1, at 1575.42 MHz, and L2, at 1227.6 MHz (newer satellites also broadcast on L5 at 1176 MHz).
What is the output of a GPS sensor?
GPS receiver module gives output in standard (National Marine Electronics Association) NMEA string format. It provides output serially on Tx pin with default 9600 Baud rate. This NMEA string output from GPS receiver contains different parameters separated by commas like longitude, latitude, altitude, time etc.
What are tracking methods?
Tracking over time involves matching objects in consecutive frames using some kind of information. Essentially, object-tracking methods attempt to identify coherent relations of image information parameters (position, velocity, color, texture, shape, and so forth) between frames.
What is the type of tracking?
Vehicle tracking, with either cellular or satellite networks, is probably one of the most common types of GPS tracking. Cell-based vehicle tracking is more common than satellite tracking. This system uses a device to capture data from the vehicle and then reports the data by using cell towers.
Does a GPS tracker need a battery?
Like hardwired systems, Plug and Play GPS trackers get their power from your vehicle’s electrical system, so they don’t require batteries either. For example, you can get engine diagnostics like vehicle speed, distance driving, maintenance reports, etc., and even immobilize your car remotely if it’s stolen.
What is GPS L1 and L2 frequency?
Each GPS satellite transmits data on two frequencies, L1 (1575.42 Mhz) and L2 (1227.60 MHz). The atomic clocks aboard the satellite produces the fundamental L-band frequency, 10.23 Mhz.
