The ADOP and PDOP: Two Complementary Diagnostics for GNSS Positioning [PDF]

Journal of Surveying Engineering, - ASCE, 2020
Ambiguity dilution of precision (ADOP) and position dilution of precision (PDOP) are two popular scalar-diagnostics used in Global Navigation Satellite System (GNSS) positioning. Where the ADOP is a predictor for carrier-phase ambiguity resolution performance, the PDOP is meant to predict the receiver-satellite geometry's capability for precise ...

PDOP parameters improvement using multi-GNSS and signal re-transmission at lunar distances

Advances in Space Research, 2021
Abstract Precise navigation for satellites of any kind is the key to future cost-effective Lunar missions. The usability of Global Navigation Satellite Systems (GNSS) for such high-altitude applications is still challenging due to reduced signal power levels, satellites visibility or signal processing complexity with all that resulting in a low ...

Distributed PDOP Coverage Control: Providing Large-Scale Positioning Service Using a Multi-Robot System

IEEE Robotics and Automation Letters, 2021
This manuscript addresses the active positioning service using a multi-robot system (MRS) for providing large-scale coverage and scalability in terms of MRS size. Inspired by the coverage control problems from Wireless Sensor Network (WSN) literature, we propose a gradient-based control method where a position dilation of precision (PDOP) field is ...
