There is no question as to why you get 8 with SOLO and 18 with the others. SOLO does not receive GLONASS. The question is as to whether K is smaller, taking into account all the factors that go into it, with the addition of the 10 GLONASS satellites or not. If it is then the design of SOLO is...

As I tried to explain in my last post what you ultimately care about is not what the geometry will allow (A; DOP) or what the signal to noise ratio and multipath give you for individual satellite range error (Kn) or how well WAAS has corrected the ephemerides (Kp) but the combined effect of all...

At a very high level the error in the vehicle's estimated position is K = (1/A)*Kn*(1/A_) + B*(1/A)*Kp*(1/A_)*B K is in units of ft^2. Kn is also in units of ft^2 and represents the error the receiver makes in estimating the pseudorange to the satellites. HDOP is part of A. Obviously the...

Yes, at 2.4 GHz (which is a ham band - that's why you can use 5 W boosters legally if you have a license) cable losses are appreciable. The way we beat them is to put the amplifiers (for both directions) as close to the antenna as we can possibly get them i.e. at the top of the tower. The cards...

But it would be kind of hard for them to argue that a crash was caused by unusually robust received signal.

For the money? Not much question about that: DaVinci Resolve. The best color grading I have ever seen and it is free! FCP used to be real editing software but is now just glorified iMovie. Many say it is still handier than Resolve for stringing clips together and recommend it for that while you...

Common sense is a wonderful and powerful thing. It is really too bad it is so rare.

I wouldn't call them highly directional. Just the fact of 10 dbi gain implies that the beam width will be about 90 °. Various posts here and there on the net suggest that the 3 dB beam width is 60 - 70°. When the vehicle is far away you should be pointed as close to it as you can be as being off...

In Europe you have just as many GPS satellites as we do here in the USA unless there is some agreement between the US and EU that the US will turn some off when over Europe and I can't imagine why anyone would want that.

I guess I'm a little surprised at how little you know about GPS given that you use it as a professional. You seem to understand the 'strong vs weak' triangles aspect of things. A 'weak' triangle is said to have poor (a high number) Geometric Dilution of Precision (GDOP) and conversely for a...

When they pulled that subscription nonsense with Photoshop they lost this customer. I now use GIMP. Never did use Premiere but didn't think too highly of Apple when then converted FCP into iMovie +

What do you get for color grading with Elements? Does it approach Resolve?

The big advantage the inverter has is that he's already got it.

Under normal circumstances you plug the charger into a wall outlet from which it takes AC current and converts that to DC current which it supplies to the battery over time at a level appropriate to the charge status of the battery - a fairly hefty current at first and then at a tapering rate as...
