GB, refers to a gigabyte which is a unit used to measure computer storage capacity and is approximate to 1.07 billion bytes. 1 Gigabyte of data is almost twice the amount of data that a CD-ROM can hold. Additionally, 1 Gigabyte could hold the contents of about 10 yards of books on a shelf.
microSD is a format for removable flash memory cards. The cards are commonly used to hold digital data and are commonly found in cellular phones, as well as in handheld GPS devices, portable media players, digital audio players, expandable USB flash memory drives, Nintendo DS flashcards, and digital cameras.

Real-time GPS tracking systems send location updates to the Internet every 5 to 10 seconds. There is no need to retrieve the GPS device in order to get the location data, because you can view these real-time updates directly on the Internet. This let’s you follow a car or person to their approximate GPS location no matter where they are in real-time, online.
Fleet management is what a company does to organize and track an entire fleet of company vehicles. The most basic function in all fleet management systems, is the vehicle tracking component. This component is usually GPS based, triangulating a vehicles location on a map. This can be used to effectively dispatch trucks for delivery or emergency purposes. Fleet management software is either part of the GPS tracker’s capabilities or can be bought separately. Once vehicle location, direction and speed are determined from the GPS components, additional tracking capabilities transmit this information to a Fleet Management software application. Methods for data transmission include both terrestrial and satellite.
Passive GPS devices store GPS location, speed, heading that can be quickly downloaded from the device onto your computer. The device is sometimes triggered by an event such as key on/off, door open/closed. Passive GPS is commonly used with fleet management and vehicle tracking where GPS data only needs to be harvested once in awhile rather than in real-time. Once the vehicle returns to a predetermined point, the device is removed and the data downloaded to a computer for evaluation. On the other hand, active GPS devices also collect the same information but usually transmit the data in real-time via cellular or satellite networks to a computer or data center for evaluation.
A GPS logger simply stores geographic positions at regular intervals in its internal memory. Modern GPS loggers have either a memory card slot, or internal flash memory and a USB port. Some act as a USB flash drive. This allows downloading of the track log data for further analyzing in a computer.
A USB port is a standard cable connection interface on personal computers and consumer electronics. USB ports allow stand-alone electronic devices to be connected via cables to a computer. USB can connect computer peripherals such as mice, keyboards, PDAs, gamepads and joysticks, scanners, digital cameras, printers, personal media players, flash drives, and external hard drives.
Binocular vision is vision in which both eyes are used together. Binoculars give users a three-dimensional image: the two views, presented from slightly different viewpoints to each of the viewer’s eyes, produce a merged view with depth perception.
An abbreviation for “light emitting diode,” it’s an electronic device that lights up when electricity passes through it. LEDS are good for displaying images because they can be relatively small, and they do not burn out. However, they require more power than LCDs.
A covert listening device, more commonly known as a bug or a wire, is usually a combination of a miniature radio transmitter with a microphone. The use of bugs, called bugging, is a common technique in espionage and in police investigations.
Concerning a Global Positioning System (GPS) receiver, Time To First Fix (TTFF) is a specification detailing the time required for a GPS receiver to acquire satellite signals and navigation data, and calculate a position solution (called a fix).
