Key Settings and Parameters

• Observation interval: shorter (1 Hz or faster) for kinematic; 1–30 s for static/PPP.
• Elevation mask: typically 10–15° to reduce multipath and poor geometry.
• Ionospheric/tropospheric models: select appropriate models or apply external corrections if available.
• Satellite systems: enable GPS+GLONASS+Galileo+BeiDou as supported to improve geometry and robustness.
• Ambiguity resolution: enable integer ambiguity fixing and inspect fix ratio statistics.

Top Candidate 1: CompassGNSS (Android App)

This is the most common result for users looking for a modern, mobile solution for GNSS data logging and processing.

What it is: A professional tool for Android devices that allows users to connect to external GNSS receivers (via Bluetooth or USB) to log raw data (RINEX) and perform post-processing.

Review:

• Pros:
  • Cost-Effective: It is often free or low-cost compared to desktop suites, making it highly popular among independent surveyors and researchers.
  • Portability: Turns your Android phone or tablet into a data collector and logger.
  • Format Support: Exports to RINEX, which is the industry standard, meaning you can process the data in other software (like RTKLIB) later.
  • UI: The interface is clean and technical, providing satellite skyplots, signal-to-noise ratios, and PDOP values in real-time.
• Cons:
  • Hardware Dependent: You need a high-quality external GNSS receiver (like a u-blox or Hemisphere board) to get survey-grade results; the phone's internal GPS is not accurate enough for professional work.
  • Learning Curve: It assumes you understand terms like "Epoch Interval" and "RINEX conversion."
• Verdict: Essential for mobile surveyors. If you have an external antenna and want to log raw data for free/cheap, this is the gold standard on Android.

What Compass Solution Does

• Converts raw GNSS observation files into precise positions.
• Supports differential processing (base/rover), network adjustments, RTK, and PPP (precise point positioning).
• Applies precise satellite ephemerides and clock products, antenna models, and ionospheric/tropospheric corrections.
• Exports results in common formats (RINEX, CSV, NMEA, shapefiles, etc.) for GIS and surveying workflows.

Step-by-step:

1. Export from Compass – Use ASCII or CSV with all survey columns (MD, inc, az, TVD, NS, EW, DLS, BtnDist, etc.).
2. QC & Cleaning – Remove duplicates, flag spikes in inclination/azimuth, interpolate missing depths (linear or spline).
3. Error Correction – Apply:
   • Multi-station analysis (MSA) for magnetic interference.
   • Geomagnetic reference update (IGRF model update).
   • Sag correction from BHA data.
4. Reformat & Merge – Convert to WITSML, LAS, or operator-specific format; merge with real-time surface data (WOB, RPM, GPM).
5. Visualization – 3D wellpath plot, plan vs. actual deviation, DLS heatmaps.
6. Reporting – Generate PDF/Excel with error ellipses, separation factor tables.
