: Option to switch from Broadcast orbits to Precise orbits (SP3 format) downloaded from the International GNSS Service (IGS) for long baselines. 3. Network Least-Squares Adjustment
This tool allowed users to determine the best time of day for data collection by simulating satellite positions. A key advantage was its support for both the US and Russian GLONASS constellations, a relatively advanced feature at the time that could significantly improve satellite visibility and overall solution geometry.
| Feature Category | Specific Capabilities | | :--- | :--- | | | Determines the optimal satellite visibility and time for data collection | | Data Transfer | Downloads raw survey data from Ashtech field equipment to the office PC | | Vector Processing | Processes raw data into baseline vectors; supports Static, Rapid Static, Pseudo-Kinematic, Stop&Go, and Continuous Kinematic modes | | Quality Control & Analysis | Includes Blunder Detection (unique site ID test, antenna height test, etc.) and Quality Analysis (loop closure analysis, automatic repeat vector analysis, etc.) | | Least-Squares Adjustment | Adjusts vectors to isolate errors, compute redundant point positions, and determine overall survey accuracy using chi-square and tau tests | | Datum & Grid Transformation | Integrated transformations for processing, reporting, and exporting in user-defined systems using 7-parameter datum methods |
In the world of geomatics, surveying, and precision navigation, the software that processes raw data is just as critical as the hardware that collects it. For over a decade, has remained a cornerstone for professionals dealing with GPS and GNSS post-processing. While newer versions and competing software exist, version 2.6 holds a unique place in the industry for its stability, specific feature set, and legacy hardware support. Ashtech Solutions 2.6
: Typically set between 10° to 15° to filter out noisy, low-horizon satellite signals.
The software was widely used in various scientific and commercial fields, including:
Run network adjustment to calculate final coordinates. Reporting: Generate a final report of the survey results. Legacy and Transition to GNSS Solutions : Option to switch from Broadcast orbits to
After securing high-quality fixed baselines, the least-squares adjustment is run. The software then generates comprehensive text or HTML reports detailing closure errors, adjusted coordinates, and error ellipses for every surveyed point. Technical Specifications and System Compatibility
Processing static data to establish or densify control points in regional surveying projects.
Define control points by entering known coordinates for fixed reference stations. A key advantage was its support for both
However, for legacy projects and those using older Ashtech hardware, Ashtech Solutions 2.6 remains a powerful and accurate tool. Conclusion
Because Ashtech Solutions 2.6 was built for 32-bit Windows architectures (optimally Windows XP), executing the software on modern 64-bit operating systems requires specific compatibility steps:
In the world of high-accuracy surveying and geodetic engineering, the software you use to post-process your raw GNSS (Global Navigation Satellite System) data is just as important as the hardware in the field. For decades, professionals have relied on a suite of robust tools to convert satellite signals into actionable, centimeter-level coordinates. Among these legacy titans sits .
