What's The Differences Between the 5 GNSS Constellations?

Posted by Rob Rutkowski on Jan 25, 2022 8:30:00 AM

Before we dive into the differences between the 5 GNSS constellations... It's important that we're all on the same page with the difference between GNSS and GPS.

Many people get GNSS and GPS technology confused. A good way to think about the Global Navigation Satellite Systems (GNSS) is as the backbone (or underlying technology) behind GPS. The Global Positioning System (GPS) GPS is a GNSS constellation, but GNSS is not always GPS. GPS is one of the 5 GNSS constellations used around the world.

The 5 GNSS constellations include GPS (US), QZSS (Japan), BEIDOU (China), GALILEO (EU), and GLONASS (Russia). We'll cover each of these constellations in-depth in this post.

9 Best Space Podcasts for Space Geeks

Posted by Rob Rutkowski on Jan 25, 2022 7:50:00 AM

Space podcasts are becoming very popular, and for good reason. The space industry has been 'skyrocketing' in recent years. SpaceX showed the world it's possible to reuse a space shuttle. Companies like OneWeb are now revolutionizing satellite communications technology. There are even companies planning out the colonization of mars and using asteroids as a source of water. 

We are quickly learning more and more about the deep depths of outer space...now more than ever. Following some of the best space podcasts can be a great way to keep up with the latest space technology, space exploration, and space science. Let's explore a few!

How to Choose the Best Wireless IoT Connectivity Option

Posted by Rob Rutkowski on Aug 26, 2021 9:30:00 AM

According to Statista,  there is a projected 30 billion Internet of Things (IoT) devices to be connected by 2020. That would be over a 400% increase in connected IoT devices from 2014. Most of these IoT devices will need to be connected through at least one type of wireless radio frequency (RF) communication.

The Secret to Low Phase Noise in Crystal Oscillator Circuits

Posted by Rob Rutkowski on Aug 26, 2021 9:06:00 AM

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.

Crystal Oscillators: The Beginners Guide (OCXO, TCXO, VCXO, Clocks)

Posted by Rob Rutkowski on Aug 9, 2021 7:03:00 AM

We'll be honest, crystal oscillators aren't the easiest topic to understand. That's mostly because there's a wide variety of crystal oscillator types that do different things, in different ways, for different purposes. This is largely due to the almost endless application uses. From satellite communications in space, to military & defense, to telecom and more... there's so many different needs for crystal oscillators. 

In this post we'll cover the most common types of crystal oscillator which include

  • Oven controlled crystal oscillators (OCXO)
  • Temperature compensated oscillators (TCXO)
  • Voltage controlled oscillators (VCXO)
  • Clock oscillators (XO)
  • And some other key types within each category

I know it sounds like a lot to cover, but don't worry! We're about to make things a whole lot easier for you. By the end of this post you'll learn the basic uses, advantages, and limitations of each crystal oscillator type.

Top 8 Cost Drivers of Crystal Oscillators (How to Save on Costs)

Posted by Rob Rutkowski on Jul 13, 2021 8:15:00 AM

One of the key things you need to know before purchasing a crystal oscillator is expected costs. There are multiple ways and specifications that can quickly drive up (and down) the costs of OCXOs and other crystal oscillators. In this post, you'll learn the top 8 cost drivers for crystal oscillators in order of most influential to least influential.

By the end of this post you'll have a much better idea of where to focus your cost-cutting efforts and to save the most in the long-term. Much of it just depends on your specific application and needs and where you're able to be more flexible.

Note: Oscillator pricing is very dependent on your specific needs and application. Be sure to contact us for specific information and pricing based on your needs.

5 FAQs About Low Earth Orbit (LEO) Satellite Constellations

Posted by Rob Rutkowski on Jun 15, 2021 7:50:00 AM

 

With the recent start of the new space revolution and the rapid growth of Low Earth Orbit (LEO) constellation technology in recent years, there have been tons of questions being asked as to what all these new LEO satellite innovations and technologies are all about.

In this post, we're going to answer:

  • What exactly is the purpose of these large LEO constellations?
  • Why are so many satellites needed?
  • How are LEO satellites different from traditional satellites?
  • Which frequency bands will these constellations operate on?
  • Who are the current major players in this space? (No pun intended)

Trust me, you’re going to want to know ALL of the answers with so much talk happening right now around this topic.

Buy OCXOs - Immediate Oscillator Pricing for Design Engineers

Posted by Rob Rutkowski on Oct 6, 2020 8:30:00 AM

Have you noticed how difficult it seems to find transparent pricing for frequency control & crystal oscillator components? If so, you're not wrong. Traditionally, it has been difficult to find quick, standard pricing for all things frequency control. Instead, you're basically forced to go through the long quoting process to even get an idea of expected pricing. So why is this? In this post I'm going to explain why OCXO oscillator pricing has been traditionally hard to find, and how Bliley's innovative pricing approach will make your procurement process so much easier.

Also, be sure to check out our OCXO immediate pricing guide at the end of this post!
