Welcome to part 3 of my series on OSNMA, the proposed Galileo Navigation Message Authentication protocol. This part can be read independently from part 1 and part 2, but it might be useful to read the introduction to part 1. This post...
We horen veel over hoeveel mensen er nu besmet raken met COVID-19. Tegelijk viel het tot begin oktober erg mee met de ziekenhuisopnames en sterfgevallen. Ik kan ook niet verklaren hoe dat precies komt (het is niet alleen leeftijd), maar...
Recapping from part 1: Galileo will soon add cryptographic signatures to the navigation messages. These cryptographic signatures are made with symmetric cryptography, which means clever techniques are required to prevent receivers from...
Position, velocity and time (PVT) information can be a ’nice to have’, but in other circumstances knowing place and time has legal or military importance as well. Heavy vehicles for example are typically outfitted with tachographs that...
Toch weer een kleine Corona-update, vrij snel na de vorige van 1 juli. Want poeh, gaat het nou ineens weer mis in Nederland? Of valt het mee? Moeten we allemaal aan de maskers en komt het dan goed? En gaan de vaccins en medicijnen ons...
GPS, GLONASS, Galileo, BeiDou (Global Navigational Satellite Systems, GNSS) are miracles of engineering. And within any complex system hide surprises and unsuspected complications. In this post I go over how we resolved an odd...
Hi everyone, Disclaimer: this is a review of a free sample I got sent by Uputronics. I recently spotted on Twitter that Uputronics had launched a GPS/RTS Raspberry Pi Expansion Board, and that they were looking for worthy projects to...
I have a longer story brewing, but in this post I want to briefly announce the “Galmon.eu unofficial Weekly Performance Report”. This is a blog post version of an earlier Twitter thread. I’m very proud to present the first full Galmon.eu...
Nu het RIVM gestopt is met dagelijkse updates vond ik dat het tijd was dat gat dan maar te vullen, al is het maar voor een dag. Een nieuwe Corona Update “hoe gaat het nu met”. De vorige was alweer van 21 april! De “Ik ben geen expert,...
When COVID-19 burst on to the scene, tests quickly showed that the everyone was susceptible - no pre-existing antibodies were found that bound to the SARS-CoV-2 virus. This led to dire predictions that over 80% of the population might...
Welcome to this post, in which we’ll be taking a trip through the wild and bumpy ride that has been Vitamin D & sunlight research over the past few decades, and what it might mean for COVID-19. As with my previous post, before any...
It turns out that so far, I have written over 44000 words on COVID-19. I’ve tried very hard to only report the best and most trustworthy science, but I did strive to include interesting new insights that were not yet mainstream. As an...
This post is dedicated to lab technicians everywhere doing the difficult work institutes and hospitals rely on to investigate disease and keep us healthy. Lab work requires high precision, deep understanding, is physically demanding, and...
Before any non-specialist attempts to write something on COVID-19, we should wonder: are any actual experts already writing on this, and if not, why not. Enough badly informed stuff has already been published by amateurs that before...
Een spontane wetenschapsupdate, omdat het Moederdag is, en speciaal voor iedereen die het nu zonder zijn of haar moeder moet doen. Want, we dragen allemaal letterlijk een beetje onze moeder bij ons! Deze post is dankbaar geïnspireerd...
