Description and Operation

Introduction

DELTA-3 is a powerful and reliable receiver for 

high-precision navigation systems, including high dy-

namics systems, for machine and traffic control, as well 

as for high-precision surveying and geodynamics and 

aerogeophysics applications. 

864 GNSS channels of this receiver allow tracking 

all current and future satellite signals. DELTA-3 is the 

only receiver in the market that can track and decode 

the QZSS LEX signal messages. 

DELTA-3 can operate as a receiver for post-pro-

cessing, as a Continuously Operating Reference 

Station (CORS) or portable base station for Real-time 

Kinematic (RTK) applications, and as a scientific sta

-

tion collecting information for special studies, such as 

ionosphere monitoring and the like (Fig.  1). 

Figure 1. 

DELTA-3 

DELTA can receive and processes multiple signal 

types (including GPS C/A, P1, P2, L2C (L+M), L5 

(I+Q); Gallileo E1 (B+C), E5A (I+Q), E5B (I+Q), 

AltBoc, E6; GLONASS C/A, L2C, P1, P2, L3 (I+Q); 

QZSS C/A, L1C(I+Q), L2C (L+M), L5 (I+Q), SAIF, 

LEX ; BeiDou B1, B2, B3; SBAS L1, L5 signals) im-

proving 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), increas-

ing 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 pro-

vide users accurate and precise positioning, a require-

ment 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 princi-

ples, allowing you to get the most out of your receiver.
