Magellan develops and distributes vehicle navigation, crossover GPS, and outdoor handheld navigation products. The Company also produces customized mapping software for topographic, marine, and street navigation. Current GPS products as of 2016 include: The Magellan RoadMate and Magellan Maestro series of portable car navigation systems
The digital antenna array has 24 elements; all are used for reception, while 16 are used for creating virtual receiver beams through digital beamforming. The beams' vertical elevation, and compensation for ship movement, is done electronically. [1] Horizontal training is done by mechanically rotating the entire array. [citation needed]
Smart antennas (also known as adaptive array antennas, digital antenna arrays, multiple antennas and, recently, MIMO) are antenna arrays with smart signal processing algorithms used to identify spatial signal signatures such as the direction of arrival (DOA) of the signal, and use them to calculate beamforming vectors which are used to track and locate the antenna beam on the mobile/target.
There are three-terminal antenna types available: The FB150 antenna (291 × 275 mm), commercially launched in 2009, is capable of 150 kbit/s, the FB250 antenna (329 × 276 mm) is capable of 284 kbit/s, the FB500 antenna (605 × 630 mm) capable of up to 432 kbit/s. The latter two commercially launched in 2007.
Digital antenna array (receiver segment) Digital antenna array (transmitter part) Digital antenna array (DAA) is a smart antenna with multi channels digital beamforming, usually by using fast Fourier transform (FFT). The development and practical realization of digital antenna arrays theory started in 1962 under the guidance of Vladimir Varyukhin .
Mobile satellite communications – Satellite communications systems use a directional antenna (usually a "dish") pointed at a satellite. The antenna on a moving ship or train, for example, must be pointed based on its current location. Modern antenna controllers usually incorporate a GNSS receiver to provide this information.

Commercial marine radar display. Land areas are shown in yellow, and vessel tracks are displayed with green "tails" on the screen. Marine radar systems can provide very useful radar navigation information for navigators on board ships. The ship's position could be fixed by the bearing and distance information of a fixed, reliable target on the ...
