GPS disciplined oscillators (GPSDO) are some of today's most trusted and accurate sources of timing. These powerful devices (sometimes called GPS clocks) consist of a high-quality stable oscillator and a GPS receiver. The GPSDO works by disciplining (or steering) the oscillator output to a GPS device or GNSS satellite signal via a tracking loop.

Quartz crystal oscillators are the high and mighty option for low phase noise and added frequency stability in circuit design. Yes, simple oscillators like those made with resistor-capacitor (RC) or inductor-capacitor (IC) resonators are fine for some circuits. But if you're dealing with higher performance applications in aerospace, military, and space industries... you're going to want a higher performance crystal oscillator that can maintain low phase noise & strong stability. Otherwise, you'll risk deviating from the very specific (and many times critical) center frequency selected for your design.

There is often some confusion as to which timing device would work best in satellite communication applications. Should you use a standard oscillator, GPS Disciplined Oscillator (GPSDO), or atomic clock (cesium and rubidium) in your satellite application?

Bliley Technologies has been recognized in the frequency control industry as one of the premier suppliers for high quality OCXOs for over 85 Years. Bliley has been moving up the value chain from an RF system perspective. Within the last year, Bliley has developed a commercial LEO solution to provide a master reference oscillator which provides the functionality of a PLL and OCXO from the GPSDO design and is currently in production.

Here’s the scary thing…
Even if you sit for hours upon hours trying to set a precise initial frequency of an oscillator, it’s still going to drift and the oscillator will not be able maintain that frequency over the full course of its use. In this post, you’ll learn the MANY sources of frequency instability and why an Ultra-Stable OCXO may be the fix-all solution.

One Size Does NOT Always Fit Well
When it comes to crystal oscillators, one size does not fit all. Different applications have different power requirements, ranges of phase noise, tolerance for acceleration sensitivity, and more. As a result, different types of crystal oscillators have been developed over the years and are all used for many different applications.
