About this file
This document from Westchester County appears to be a technical specification sheet detailing requirements for alternate brands/items, specifically focusing on precise technical specifications for GPS/positioning equipment. The document outlines accuracy standards for different positioning modes (Static, PPK, and RTK), with specific horizontal and vertical measurement tolerances ranging from 4-14 mm plus parts per million. Additionally, the specification includes detailed technical requirements for radio communications, including LoRa radio (868/915 MHz, up to 8 km range), UHF radio (410-470 MHz), and LTE modem capabilities.
The technical specifications cover multiple communication bands and protocols, including FDD-LTE bands 1-28 and 66, TD-LTE bands 38, 40, and 41, and UMTS/WCDMA frequencies. The document emphasizes that any alternate brands or items submitted must precisely meet these comprehensive technical specifications, with particular attention to accuracy measurements, radio frequency ranges, power output, and global communication band compatibility. The specifications appear designed for a precise technological procurement process, likely for surveying, mapping, or geospatial data collection equipment.
