Oct 1, 2025Month: 2025-10 — GeoNet/delta monthly summary. This period focused on delivering GNSS infrastructure improvements, expanding equipment compatibility, and tightening data governance. Key features include Zephyr 3 Base antenna model support for sitelog generation with visual representation, and a new SMRG GNSS station with full component configuration. A hardware upgrade to Trimble Alloy for GNSS receivers was completed, alongside data cleanup for the FALE station decommission. Automation of configuration updates was also advanced to keep system state aligned with hardware and antenna model changes. These efforts drive broader data usability, improved reliability, and reduced maintenance overhead.

Mar 1, 2025March 2025: GeoNet/delta - Data quality and consistency focus. Primary accomplishment: fixed receiver data consistency by renaming GLDB to Alloy across multiple CSV sources and updating entries to reflect the Alloy designation, ensuring a single canonical label across datasets. This reduces downstream data quality risk and aligns analytics pipelines. No new features delivered this month; emphasis on data governance, reliability, and maintainability. Key commit: 52bc8d20456094747c4357fb449404157f8ae0ae.
