Let’s be honest: most spectrum analyser screens I see in the field are set up wrong. Engineers stare at a blur of noise, tweak a knob, and call it a day. But if you’re responsible for a satellite link—whether it’s a teleport, a flyaway, or a permanent earth station—you need to know what that squiggly… Read More: How to Get a Clean Satellite Spectrum Reading (Without Losing… »

I’ve spent more hours staring at a spectrum analyzer screen than I care to count, often in the back of a van with a lukewarm coffee balanced on a rack panel. The first thing you learn in the field is that a clean spectrum display doesn’t always mean a clean signal. The second thing you… Read More: How to Perform a Satellite Spectrum Analysis That Actually Means… »

I still remember the first time I hooked up a spectrum analyzer to a dish on a rooftop in Gothenburg. The screen was a mess of spikes and noise, and the client was convinced his LNB had died. It hadn’t. A 4G base station half a kilometre away was flooding the IF with interference. That… Read More: A Field Guide to Satellite Spectrum Analysis »

Point a dish at the sky and you’re not just locking onto one clean signal. You’re cracking open a window onto a packed orbital arc where dozens of satellites sit shoulder to shoulder, each bleeding a little into the next. I’ve spent years on the ground, lining up antennas and chasing signal-to-noise ratios, and I… Read More: The Problem With Ignoring Adjacent Satellite Interference »

I once watched a $2.3M Ka-band terminal sit dark for six weeks. The commissioning crew couldn’t reproduce a 1.2 dB cross-pol degradation that only showed up during morning fog. The test procedure said: Verify cross-polarization isolation meets specification. It didn’t say how. Not at what elevation, not under what atmospheric conditions, not with what reference… Read More: How to Write Satellite Ground Station Test Procedures That Don’t… »

You’ve been there. Staring at a spectrum analyzer, the noise floor looks flat and innocent. The carrier-to-noise ratio (C/N) matches the link budget perfectly. Yet the demodulator refuses to lock, and the bit error rate (BER) keeps climbing for no obvious reason. I’ve found myself in that exact situation more times than I’d like to… Read More: The Hidden Cost of Ignoring Adjacent Satellite Interference in Modern… »

If you’re planning a ground station for a low Earth orbit constellation, you’ll soon find out it’s not as simple as bolting a dish to a roof and hoping for the best. The sheer number of satellites, their speed across the sky, and the need for uninterrupted data flow force you to think differently than… Read More: How to Design a Satellite Ground Station for LEO Constellations »

From Backyard Hobbyist to Mission-Critical Infrastructure I still remember the first time I tracked a NOAA weather satellite with a handheld Yagi and a software-defined radio dongle that cost less than a takeaway pizza. The thrill of pulling a live image from space, crackly and faint as it was, never really leaves you. But when… Read More: Designing a Ground Station for LEO Constellations: A Practical Engineering… »
