Description and Operation
Principles of Operation
DELTA can receive and processes multiple signal types (including GPS C/A, P1, L2C (L+M), P2, L5
(I+Q), Galileo E1 (B+C), E5A (I+Q), E5B (I+Q), AltBOC, GLONASS C/A, L2C, P1, P2, L3 (I+Q),
QZSS C/A, L1 (I+Q), SAIF, L2C (L+M), L5 (I+Q), Compass B1, B2, SBAS L1, L5 signals) improving
the accuracy and reliability of your measuring points and positions, especially under difficult jobsite
conditions.
The GNSS component of DELTA receivers means you can access the GPS (Global Positioning System)
satellites of the United States, the Galileo (an upcoming global positioning system maintained and
operated by Galileo Industries), the GLONASS (Global Navigation Satellite System) satellites of the
Russian Federation, the QZSS (is a proposed three-satellite regional time transfer system and Satellite
Based Augmentation System for the Global Positioning System, that would be receivable within Japan),
and the Beidou Compass (Chinese Global Navigation Satellite System), increasing the number of
satellites your receiver can detect, thus improving the accuracy of your measuring points, increasing
productivity, and reducing cost.
Several other features provide under-canopy and low signal strength reception. The DELTA receiver
provides the functionality, accuracy, availability, and integrity needed for fast and easy data collection.
Measuring with the right GNSS receiver can provide users accurate and precise positioning, a
requirement for any measuring project. This section gives an overview of existing and proposed Global
Navigation Satellite Systems (GNSS) and receiver functions to help you understand and apply basic
operating principles, allowing you to get the most out of your receiver.
