Ashtech Solutions 2.6 !!top!! -

Ashtech Solutions 2.6 is a legacy post-processing software suite designed for surveying and Global Navigation Satellite System (GNSS) data management . Developed by Ashtech (later part of Magellan and Spectra Precision), version 2.6 was a critical tool for surveyors using L1/L2 GPS and GLONASS receivers to achieve high-precision results through differential correction . Key Features and Capabilities

Ashtech Solutions 2.6 provides a comprehensive "field-to-finish" workflow within a user-friendly Windows interface . Its primary functions include:

Survey Mission Planning: Allows users to plan satellite visibility and geometry (PDOP) before heading into the field .

Automatic Vector Processing: Automatically processes raw GNSS data to calculate precise vectors between survey points .

Network Adjustment: Performs rigorous least-squares adjustments to ensure consistency across a survey network .

Data Analysis & Quality Control: Includes tools for viewing raw data plots and performing configurable quality assurance tests to identify and remove cycle slips or noisy data . Ashtech Solutions 2.6

Coordinate Transformations: Supports a vast library of predefined global and local coordinate systems, as well as user-defined transformations .

Reporting: Generates standard RTF-formatted reports that include data parameters, maps, and graphs, which can be edited in standard word processors . Common Applications

The software was widely used in various scientific and commercial fields, including:

Precision Surveying: Calculating UTM coordinates with high accuracy for infrastructure and land boundary projects .

Ecological Research: Used by researchers to accurately locate equipment (like microphones and loudspeakers) in challenging environments like thick forest canopies using differential correction . Ashtech Solutions 2

GIS Data Collection: Transforming field-collected data into industry-standard formats like DXF or SHP for use in Geographic Information Systems . Technical Specifications & Legacy Z-Xtreme GPS Receiver

Phase 5: Network Adjustment

Once all baselines in a network have fixed ambiguities, you need a weighted least squares adjustment.

Click Adjustment > Create Network.
Fix the known control point (set its coordinates as fixed).
Select "Weight by baseline length" or "Weight by variance."
Run the adjustment. The output will list adjusted coordinates with standard deviations.

9. Availability Today

Ashtech Solutions 2.6 is abandonware. It is no longer sold or supported. Copies may still be found on old survey PCs or archived disks. Running it on modern Windows requires: Phase 5: Network Adjustment Once all baselines in

Virtual Machines: Windows XP Mode in Windows 7/10/11 (using Hyper-V or VirtualBox).
Legacy Hardware: An old laptop with Windows XP and a serial port.

Users are strongly advised to migrate to modern post-processing software (e.g., RTKLIB open-source, GrafNav, or Trimble Business Center) for new projects.

4. Operational Assessment & Compatibility Issues

While Ashtech Solutions 2.6 was an industry standard in its time, its deployment in a modern IT environment presents specific challenges:

Common Troubleshooting & Error Messages

Even robust software has quirks. Here is how to fix frequent errors in Solutions 2.6:

Error: "Not enough common satellites"

Cause: Your base and rover logged data at different times.
Fix: Ensure both files have overlapping time spans. Use Edit > Trim Epochs to align them.

Error: "Cycle slip detected on L2"

Cause: Loss of lock due to signal blockage.
Fix: Manually delete the affected epochs or use the Repair Cycle Slip tool, which interpolates using L1 data.

Warning: "Solution is Float only"

Cause: Poor geometry or noisy data.
Fix: Lengthen the observation period (if static) or move to a more open sky location.
