Base station deviation calculation

How should a base station be positioned?

Base stations should use fixed height tripods and be on opposite sides of the project, if possible. Baselines ≤ 10 KM (6 miles). Data collected at a 1-second interval for 3 minutes (180 epochs), PDOP ≤ 2.0, ≥ 7 satellites, position solution RMS ≤ 0.01 m. No multipath conditions observed.

Is there a standard for a base station antenna?

The BSA’s influence on coverage, capacity, and QoS is extensive, and yet there exists no comprehensive, global, standard focusing on the base station antenna. The purpose of this whitepaper is to address this gap. In particular, the following topics will be covered in various degrees of detail:

Why is a base station considered a 'truth'?

With a base station considered as coordinate “truth,” the precisions of the observations taken at the rover reflect the accuracy to this truth. That is, the precision is the measure of local accuracy. If constraints have been applied to local passive monuments, it is important the base station be related to the localization performed.

Why do we need additional base stations in case a?

In Case A, a new demand is created in each period in addition to the demand of previous periods. Hence, additional base stations (BSs) may be needed to satisfy the new demand.

How is a satellite estimate based on a noise reduction filter?

Estimates are run through measurement noise reduction filters. Differencing reduces or eliminates satellite clock errors, receiver clock errors, satellite hardware errors, receiver hardware errors, and cycle slips. Integer ambiguity search is started. Frequency combinations narrow the field of candidates.

What is the operating environment of a base station antenna?

The operating environment of base station antennas is classified as remote, stationary, outdoor, uncontrolled and not weather-protected. The electromagnetic environment includes close proximity to intentionally radiating devices and installation on structures prone to lightning strikes.
