Advanced Pet Tracking GPS System

As a pet owner, I'm looking for a reliable GPS engineer who can specialize in creating an advanced GPS system tailored for tracking pets. The key tasks required include:

- Thorough GPS signal processing
- Designing a satellite navigation system
- Calibrating GNSS receiver

The primary purpose of this GPS system is to keep a consistent eye on pet's location and activities. This involves the vital need for a GPS system with the capabilities of:

- Real-time tracking, giving instant location updates
- Geo-fencing capability, allowing to set territorial limits for the pet
- Long battery life, necessitating minimal recharges

The perfect candidate for this project will have significant experience in GPS system design, GNSS receiver calibration and GPS signal processing. Familiarity with pet behavior and needs or prior experience in designing pet-related technology would be a plus.

My main aim is to keep my pets safe, and their exact location known at all times, anywhere. It's essential for the device to have a strong battery life to permit uninterrupted service and a flexible geo-fencing capability to ensure pet safety.

Kindly share your relevant experience and let me know how you can aid in the realization of this project.
