GPS & GLONASS Seamless Integration
    With the addition of GLONASS to its leading GPS technology, Magellan has expanded the availability, integrity and accuracy of global positioning tools. The GG24-E2GPS board adds another satellite constellation, GLONASS (the Russian equivalent to GPS), to the solution for precise positioning. The GG24-E2 is the first all-in-view GPS+GLONASS receiver. Its revolutionary design allows smooth integration into a wide range of positioning applications on land, sea or in the air. Incorporating the GG24-E2 is simple because of our advanced patented methods to blend GPS and GLONASS into a single navigation position solution or RTK position solution. The sophisticated combination of the technologies is transparent to the user. The GG24-E2 is capable of tracking negative frequency GLONASS channels and uses all available satellites from both systems to obtain the best position information. The GG24-E2 GPS and GLONASS RF sections are independent, so any interference on the GLONASS frequencies will not affect GPS, and vice-versa.
    Increased Availability
   One of the primary advantages of GPS+GLONASS is the increased number of satellities from the combined constellations available for position computation. Thus, GPS+GLONASS is extremely beneficial in obstructed operating environments, such as in cities around buildings, mountainous areas, under tree cover, or other areas where much of the sky and many of the satellites can be blocked. To take advantage of the increased satellite availability, the GG24-E2 from Magellan has 12 channels for L1 GPS and 12 channels for L1 GLONASS, providing all-in-view tracking for both constellations.
    Improved Integrity
    By using GPS+GLONASS, users benefit from the integrity of two independently operated satellite positioning systems. With more satellites available, the constellation geometry is significantly improved, providing users with added confidence in the accuracy of the positioning solutions.
    Windows Evaluation Software
    Evaluate software is available with the GG24-E2 and provides visual displays of satellite information (e.g., SNR), receiver position and velocity, as well as data logging and analysis. It also allows direct communication with the receiver. Compatible with most of our receivers, the software runs on Windows version 3.x, Windows 95/98, NT, 2000, and XP platforms.
