Heading and Attitude determination: Products and Solutions

Reliable Single Frequency Carrier Phase based Attitude Determination Receiver System (SF-ADRS)

This low cost solution provides a 5 Hz heading information in real-time with a 1 sigma accuracy of 0.5°/ baseline length [m], i.e. 0.5° for a baseline length of 1 m and 0.005° for a baseline length of 100 m. The hardware system consists of two receivers with ANAVS's patented kinematic on-board phase calibration, that ensures a continuous phase solution and does not need any integer ambiguity resolution. Detailed specifications and key features of ANAVS's heading determination system are described in the datasheet.

Reliable Single and Multi-Frequency Differential Carrier Phase Positioning Software (SF/MF-DCPS)

This software package enables a kinematic carrier phase positioning with centimeter accuracy and an integer ambiguity resolution with an error rate of less than 1e-6. This high reliability is achieved by ANAVS patented MAP integer ambiguity estimation method, which uses Gaussian a priori information about the baseline length and direction, a new set of multi-frequency linear combinations, and an adaptive state space model for the movement of the receiver to further constrain the integer search space volume.
The user can set a large variety of parameters including the linear combination properties, the statistical a priori information and the state space model, which allows a performance assessment for any environment and atmospheric condition. The linear combinations are automatically optimized for an arbitrary scaling of the geometry, an arbitary scaling of the ionospheric delay, and any preferred wavelength.

Training

ANAVS is offering a variety of courses on precise and reliable positioning with GPS, Galileo, and GLONASS. The courses are divided into a group of introductary courses and a group of more advanced courses, which are designed for people who already have some experience with satellite navigation.
All courses are taught by people, who have a teaching experience of at least 5 years from university and an additional practical experience of at least 5 years. The courses are also not only pure theoretical courses, but include several demonstrations, which accelerate the understanding of your employees and let them experience immediately and interactively the effect of changing different system/ receiver parameters.

Introductory courses (8 hours/ course):

IC 1. Precise Positioning with GNSS: Tracking, phase calibration, ambiguity resolution, position determination
IC 2. RTK Positioning and Precise Point Positioning
IC 3. Attitude determination with GNSS

Advanced courses (8 hours/ course):

AC 1. Joint Tracking of carrier phases of multiple satellites on multiple frequencies
AC 2. Reliable Integer Ambiguity Resolution with multiple frequencies
AC 3. Reliable Attitude Determination with Statistical Baseline A Priori Information
AC 4. Reliable Precise Point Positioning with multiple frequencies
AC 5. Kinematic calibration of carrier phases
