Even though GNSS and electronic toll collection have been used for decades, the idea of using satellites for road tolling is relatively recent. The first successful demonstration of GNSS Road Pricing systems was given in 1994 during the ETC field trials on the A555 motorway between Bonn and Cologne (Germany) using the American NavStar GPS ...
Electronic toll collection (ETC) is a wireless system to automatically collect the usage fee or toll charged to vehicles using toll roads, HOV lanes, toll bridges, and toll tunnels. [ 1 ] [ 2 ] It is a faster alternative which is replacing toll booths , where vehicles must stop and the driver manually pays the toll with cash or a card.
A track is a trace of somewhere that you have actually been (often called a "breadcrumb trail"). The GNSS (global navigation satellite system) unit (external or internal) periodically sends details of the location which are recorded by the software, either by taking a reading based on a set time interval, based on a set distance, based on a change in direction by more than a certain angle, or ...
All major GNSS receiver chips support Galileo and hundreds of end-user devices are compatible with Galileo. [10] The first, dual-frequency-GNSS-capable Android devices, which track more than one radio signal from each satellite, E1 and E5a frequencies for Galileo, were the Huawei Mate 20 line, Xiaomi Mi 8, Xiaomi Mi 9 and Xiaomi Mi MIX 3.
GNSS-2 is the second generation of systems that independently provide a full civilian satellite navigation system, exemplified by the European Galileo positioning system. [5] These systems will provide the accuracy and integrity monitoring necessary for civil navigation; including aircraft.
Bakwena N1N4 Toll Concession [2] The Bakwena N1N4 Toll is a separate system and has been operating for the past 12 years. The e-tag system employed by Sanral is also compatible with the current Bakwena tags and may be registered with Sanral's e-toll system for use on certain sections of the N1 and N4 towards Bela-Bela, Rustenburg and Botswana.

The use of GNSS in MEO, GEO, HEO, and highly elliptical orbits is feasible only if the receiver can acquire and track the much weaker (15 - 20 dB) GNSS side-lobe signals. This design constraint, and the radiation environment found in space, prevents the use of COTS receivers. It is easier for low Earth orbit satellites to use GNSS.
Vehicle navigation on a personal navigation assistant Garmin eTrex10 edition handheld. A satellite navigation device or satnav device, also known as a satellite navigation receiver or satnav receiver or simply a GPS device, is a user equipment that uses satellites of the Global Positioning System (GPS) or similar global navigation satellite systems (GNSS).
