20 Popular Cube Satellite Companies in Today's Market

Posted by Rob Rutkowski on Feb 4, 2020 7:28:00 AM

Welcome to the new world of CubeSat Manufacturers! These small satellites are becoming more and more popular in today’s new space industry. Their increasing popularity is mostly because of their small, lightweight, and inexpensive designs. The standard 1U Cube Satellite is 10cm x 10cm x 10cm in size. However, since their inception in 1999, new Cube Satellite companies have developed more variations in size to meet desired payload levels. A 1.5U, 2U, 3U, 6U, 8U, 12U etc. are now offered to meet customer's growing specifications.

Common Misconceptions About Crystal Oscillator Stability

Posted by Bliley Technologies on Feb 2, 2020 10:14:00 AM

RF engineers would love to get their hands on ideal crystal oscillator circuits. That is, a quartz crystal oscillator that transmits at the designated frequency for the entire life of the device without any frequency deviation. Unfortunately, that ideal circuit world is a mathematical fantasy.

There are many factors that contribute to quartz oscillator stability and frequency drift issues. To prevent these problems as much as possible, having a firm understanding of precise frequency stability will help give you the tools to keep your applications performing optimally. But there's another problem...

6 Emerging PNT Technologies & Solutions of the Future

Posted by Rob Rutkowski on Jan 7, 2020 8:42:08 AM

The U.S Department of Homeland Security considers 13 of the nation’s 16 critical infrastructure sectors to be ‘critically dependent’ on PNT technology. Also, a loss of PNT would cost the U.S an estimated $10 BILLION a day. Not only do many everyday consumers use PNT & GPS on a daily basis, it's also crucial for military and intelligence operations. Other industries that strongly rely on GPS based PNT include

  • Radio communications
  • Network synchronization
  • Intelligence systems
  • Information gathering
  • Cruise missiles
  • Weapons systems
  • Electronic warfare
In this post we're going to cover some of the challenges facing PNT today as well as 6 emerging PNT technologies and solutions that will revolutionize the future.

Is a Swept Quartz Crystal Necessary in your Timing Application?

Posted by Rob Rutkowski on Dec 11, 2019 8:45:00 AM

What is a Swept Quartz Crystal?

Like many other things, radiation can impact a crystal oscillator's frequency. This is because radiation physically alters the quartz crystal inside the oscillator (changes position of weakly bound compensators that change the elastic constants of quartz). In some cases, radiation can even impact the crystal series resonance. The increase of resonance can be serious enough to cause the oscillator to stop oscillating if the crystal isn't radiation resistant. When a quartz crystal is manufactured to be radiation resistant, the crystal is referred to as a swept quartz crystal.

Warning! EFC Over-Specification May Be Costing You (Do this instead!)

Posted by Rob Rutkowski on Oct 2, 2019 11:14:09 AM

What if I told you that specifying more Electronic Frequency Control (EFC) than you need could actually be hurting you pocketbook? Well, it very well may be! Paying attention to whether your supplier is using AT cut vs SC cut crystals will help you save money in the long run with OCXOs.
