GNSS, or Global Navigation Satellite System, is the multitude of satellite navigation systems orbiting earth. The term GNSS refers to the collection of the world's global satellite positioning systems including GPS (United States), GLONASS (Russia), COMPASS (China) and Galileo (European Union).

GNSS works by translating the signal information transmitted by each satellite through a series of calculations. These signals, travelling at the speed of light, are intercepted by the receiver, which calculates how far away each satellite is based on how long it took for the messages to arrive. Whenever at least four GNSS satellites are visible and transmitting, a receiver can interpret the signals and pinpoint its location using the trilateration process. The more satellites there are above the horizon, the more accurately the device can determine its location. Novariant autosteering technology can utilize the positioning information to accurately steer the vehicle along its desired path.

Single GNSS Inputs - Novariant single-antenna autosteering controllers can receive the 3-axis positioning (X, Y, Z) information from any GNSS receiver. The GNSS positioning information can then be processed by the Novariant controllers, in combination with other integrated or non-integrated sensor inputs to achieve Novariant's legendary line acquisition, in both forward and reverse operations.

Dual GNSS Inputs - Novariant autosteering solutions using the patented dual GNSS antenna inputs feature a unique technology that can calculate position and heading even when not moving. Novariant dual GNSS steering technology can track roll and yaw at all times giving unmatched accuracy and repeatability.

Accuracy Level - Novariant autosteering solutions support all precision levels offered by the GNSS solutions including autonomous pass to pass, DGPS WAAS/EGNOS, autonomous/GL1DE®/eDiff®, OmniSTAR® XP/HP, and RTK (Radio and NTRIP/CORS).

Flexibility in GNSS Selection

Novariant controllers are universal and can receive the signals from any certified GNSS receiver in the market. Future-proof upgradability for new satellite constellations is guaranteed with Novariant advanced autosteering solutions.

GPS- The Global Positioning System (GPS) is a satellite-based navigation system consists of a constellation of 31 satellites placed into orbit by the U.S. Department of Defense. The GPS system was originally developed for military navigation but now anyone with a GPS device can receive the radio signals that the satellites broadcast.

GLONASS - Global Navigation Satellite System (GLONASS) is a space-based satellite navigation system operated by the Russian Aerospace Defense Forces. It provides an alternative to Global Positioning System (GPS) and as of July 2014 with operational satellites over 22, the only alternative navigational system in operation with global coverage and of comparable precision.

Galileo - Galileo is the global navigation satellite system currently being built by the European Union (EU) and European Space Agency (ESA). It is interoperable with GPS and GLONASS. Four operational test satellites that are designed to validate the Galileo concept are already in space. Galileo will have approximately 30 satellites by 2018.

COMPASS/BeiDou-2 - The BeiDou Navigation Satellite System is the regional Chinese satellite navigation system. It is currently offering services to customers in the Asia-Pacific region. The future China Compass navigation system is planned to become a global satellite navigation system consisting of 35 satellites and will begin serving global customers upon its completion in 2020.

IRNSS - The Indian Regional Navigational Satellite System (IRNSS) is an autonomous regional satellite navigation system being developed by Indian Space Research Organization (ISRO) which would be under the total control of Indian government. IRNSS will consist of a constellation of 7 navigational satellites.

QZSS - The Quasi-Zenith Satellite System (QZSS), is a proposed satellite regional time transfer system and Satellite Based Augmentation System for the Global Positioning System, that would be receivable within Japan. The number of QZSS satellites is planned to be four.
