Ashtech | Solutions 2.6

While newer software packages have entered the market, Ashtech Solutions 2.6 remains a gold standard for organizations using legacy Ashtech receivers (such as the Z-Series, UZ-12, or ProMark2) and for surveyors who appreciate a workflow that prioritizes control, transparency, and mathematical rigor. This article explores every facet of Ashtech Solutions 2.6—from installation and processing workflows to advanced ambiguity resolution and its place in the modern surveying ecosystem. Ashtech Solutions 2.6 is a professional GNSS post-processing software application developed by Ashtech (now part of Trimble Navigation). It is specifically designed to handle carrier-phase and pseudorange data from static, kinematic, and stop-and-go survey methods.

| Feature | Ashtech Solutions 2.6 | Modern Software | | :--- | :--- | :--- | | | Surprisingly robust for L1/L2 GPS/GLONASS | Multi-GNSS (GPS, GLONASS, Galileo, BeiDou) | | User Interface | Classic, functional, text-heavy | Modern ribbon UI, graphical, map-centric | | Learning Curve | Steep (requires understanding of ambiguity theory) | Shallow (automated workflows) | | Reporting | Excellent, detailed, transparent | Often opaque, simplified reports | | Cost | Low (used licenses / legacy support) | High ($3,000 - $8,000 annually) | | Hardware Support | Legacy Ashtech, generic RINEX | All modern receivers | Ashtech Solutions 2.6

The double difference residual plot is your best diagnostic tool. If you see a sinusoidal pattern, you are looking at multipath. If you see a drift, you have an unmodeled tropospheric effect. It is specifically designed to handle carrier-phase and
