Improving GPS Performance in Difficult Environments

Overview

Improving positioning performance in environments with weak or obstructed satellite visibility.

Technologies

GNSS | RF design | Antennas | Embedded systems

Define the Problem

A GPS-enabled system struggled to maintain reliable positioning performance in enclosed or signal-challenged environments.

Diagnose the Root Cause

Investigation showed antenna placement and surrounding structures significantly reduced signal sensitivity.

Key engineering challenges included:

• Weak signal environments

• Mechanical limitations

• Ground plane interaction

• RF sensitivity requirements

Deliver the Solution

We redesigned antenna implementation and optimised the RF layout to improve acquisition performance.

Key Outcomes

• Faster satellite acquisition

• Improved positioning accuracy

• Reliable operation in challenging environments

• Increased signal sensitivity
