How TCXOs Improve Oscillator Stability & Aging with Low Power Consumption

Posted by Bliley Technologies on Sep 3, 2024 9:00:00 AM

RF engineers are always trying to improve the performance of the systems they work on, but a perfect, 100% stable signal that never deviates from the intended frequency will probably never be attainable. The toll that the physical environment and time will take on a crystal remains a fact of life.

But that doesn’t stop us from always working towards getting as close to possible to that ideal. The effects of the physical environment and time can both be mitigated by selecting a high-quality quartz crystal oscillator. Picking the right one for the job depends on the application and other factors, like the amount of power available.

In this article, we will make the case that for those who are trying to minimize the effects of aging and improve stability without using a lot of power, a temperature compensated crystal oscillator (TCXO) might be the right solution.

GPSDOs for CubeSats & Other SmallSats: GPS Disciplined Oscillator Design & Architecture

Posted by Bliley Technologies on Jul 31, 2024 9:00:00 AM

GPS disciplined oscillators (GPSDOs) are becoming a necessary component for CubeSats and other small satellites (SmallSats).

GPSDOs are comprised of a Global Position System (GPS) receiver, an oven controlled crystal oscillator (OCXO), and a phased-locked loop (PLL). In this blog, you'll get a deeper look into how GPSDOs are designed to help achieve mission success for your small satellite applications.

GPSDOs vs. Atomic Clocks: Which Work Best for LEO, MEO, & GEO Satellites?

Posted by Bliley Technologies on Jul 22, 2024 9:00:00 AM

We've seen some confusion over which timing device works best in satellite communication applications. Should you use a standard oscillator (OCXO), a GPS disciplined oscillator (GPSDO), or an atomic clock in your satellite?

The short answer is, "it depends." You'll need to choose your timing device based on on your specific needs, limitations, and operational orbit. Let's take a look at each operational orbit (LEO, MEO, and GEO) and which types of timing devices their satellites require.

3 Types of OCXOs & How They Establish Precise Frequency Control

Posted by Bliley Technologies on May 16, 2024 9:00:00 AM

Temperature variations are the most significant factor contributing to frequency drift in crystal oscillators.

Other variables that affect frequency output, such as humidity and pressure, can be alleviated easily with a hermetically sealed packaging of the crystal in a vacuum or in an inert gas, such as nitrogen. But controlling temperature for precise frequency output in a crystal oscillator circuit requires a higher level of electronic RF design ingenuity. Enter: the oven controlled crystal oscillator (OCXO).

In this post, we'll take a look at the three types of OCXOs available for RF engineers to meet individual design priorities such as frequency precision, warm-up time, crystal aging, and power consumption.

Assured PNT: Going Beyond GPS Timing

Posted by Bliley Technologies on Nov 30, 2023 9:00:00 AM

While GPS technology plays an important role in modern navigation, it's not perfect. Although GPS might perform well enough consumer usage, signal jamming or other disruptions present serious threats to military operations. 

Enter assured positioning, navigation, and timing (A-PNT), new technology that enhances traditional GPS timing. Assured PNT uses additional sources to augment GPS and prevent vulnerabilities. Its goal is to ensure that accurate positioning, navigation, and timing (PNT) is always available.

In this blog, we'll review GPS, its flaws, and other PNT systems (like the GNSS) and give you an overview of how assured PNT technology uses other systems to improve effectiveness.
