About Our GPS Splitters

At GPS Source, our engineering philosophy begins with signal protection. A GNSS source carries extremely low-power signals, and maintaining this integrity during distribution is critical. Each of our GPS splitters is built to provide:

Exceptional Isolation
High isolation minimizes interaction between connected receivers and prevents back-feed interference.

Optimized Gain and Loss Balance
We engineer gain blocks and design architectures that ensure signal power remains within operational thresholds across all outputs.

Impedance Stability
Proper impedance matching reduces reflection, reduces noise, and preserves accuracy for both timing and navigation systems.

Reliable Power Options
Our splitters support passive, active, external power, redundant power, and DC-blocking variations, depending on your architecture.

Durable Construction
Choose from ruggedized housings, slimline enclosures, and military-grade designs for long-term durability in harsh or mission-critical environments.

These engineering priorities ensure each GPS splitter delivers consistent, predictable, high-quality performance that integrates seamlessly into your existing GNSS distribution network.
