How to Prevent Activity Dips and Frequency Perturbations in Crystal Oscillators

Posted by Rob Rutkowski on Nov 16, 2017 8:10:00 AM

Activity dips, also referred to as frequency perturbations, can be difficult to spot in oscillating crystals. However, a single activity dip can cause major problems in an application’s signal, including within GPS or missile systems. Imagine launching a missile and then losing control of its navigation. Or getting a very inaccurate GPS velocity reading of an aircraft. These (and many other problems) can be caused by a failure to spot frequency dips in crystals. It’s important to understand what activity dips are and how to avoid them from occurring in crystals...and that's exactly what you're going to learn right now!

How Does Satellite Communication Work From Space?

Posted by Rob Rutkowski on Sep 28, 2017 7:48:00 AM

The international space station (ISS) is traveling in orbit around our earth at about 217 Miles (350 km) above earth’s surface. That’s equal to about 1,148,294 feet (yes, over 1 MILLION feet) or 350,000 meters above you. Those are some crazy heights! The ISS and other satellite communication devices must be able to cover a ton of earth’s surface from there, right?

Maybe. Maybe not. Let’s explore...

20 Popular Cube Satellite Companies in Today's Market

Posted by Rob Rutkowski on Sep 25, 2017 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.
