Sunnyvale, USA, 12 February 2007 – Trimble has introduced a Global Navigation Satellite System (GNSS) receiver for agricultural users—the AgGPS 442 GNSS receiver.
The new receiver can track GLONASS and next-generation Global Positioning System (GPS) L2C satellite signals. With more satellite signals to access, the AgGPS 442 GNSS receiver improves the farmers ability to work in tough GPS environments with faster initialization times, and provides for increased productivity and reduced downtime in the field. The receiver will be showcased at the World Ag Exposition in Tulare, California.
The new GLONASS and GPS L2C processing capability from Trimble improves signal availability for high accuracy real-time kinematic (RTK) agricultural applications that rely heavily on Z, or vertical axis satellite positioning data.
It also aids RTK applications in difficult satellite scenarios such as geographic areas with limited periods of GPS signal availability. Agricultural applications that can benefit from the combined satellite signal capability include land leveling, automated guidance, and data collection for topographic mapping.
The Trimble AgGPS 442 is an integrated GNSS receiver and radio that support GLONASS, GPS L1/L2, RTK GPS and next-generation GPS L2C signals. The new receiver simply connects to the Trimble AgGPS Zephyr II antenna mounted on the roof of the agricultural vehicle or implement to provide position data to: the AgGPS FieldManager Display for topographic mapping, the AgGPS FieldLevel System and AgGPS 170 Field Computer for land leveling, and the AgGPS Autopilot System for automated guidance.
The AgGPS 442 GNSS receiver is available now from Trimble resellers.
– About GNSS, GLONASS and GPS L2C
GNSS refers collectively to the worldwide positioning, navigation, and timing determination capabilities available from one or more satellite constellations. These constellations include but are not limited to the U.S. NAVSTAR GPS, Russian Federation’s GLONASS, European Unions Galileo and complementary regional augmentation systems such as the U.S. WAAS and European EGNOS.
GLONASS is a satellite navigation system under modernization by Russia that provides free positioning; generally between one and four GLONASS satellites are in view in addition to GPS satellites. GPS refers to the U.S. NAVSTAR GPS. In late 2006, the U.S. added the second in a series of next-generation GPS satellites to the NAVSTAR constellation. These new satellites include an additional modernized civilian GPS signal, L2C, for more robust signal tracking. GNSS is an acronym used to designate receivers that support signals from multiple sources such as GPS, GLONASS, GPS Modernization (L2C) and RTK.
