Try MASM32 if you are working with windows:

You can also try GAS and NASM:

Once again, no one has asked for your opinion on feasibility. Its clear you do not have the experience to make such assessments.
Allow me to refer you to post #60:
Partially, more HPC-DSP networked with dedicated hardware to handle the grunt work.
It obvious from this statement that you cannot begin to formulate a design to compensate. As you have not worked with this type of hardware, you are not in a position to attempt sarcasm.
So, you went for...
No. The power would be recorded for each pulse as it passes through the filters, or perhaps pre-amp, stage. This is coupled with an array specifying which frequencies were detected. This is relayed to ground for analysis, correction and integration into an existing dataset.
A highly...
That's fascinating, but I meant this statement:
How did you work out that 0.04dB is the limit of modern RF Power measurement accuracy?
I'll think you will find this is orders of magnitude off, even by tech of the late 80's.
Its best to get accurate.
We're talking about high...
Go back to post #15, its explained there.
The transmitter will be located close to, or on, the Earth to a maximum altitude of about 20Km and maximum depth of 200m-300m.
That's about 10W of instability, that's outrageous. Where are you getting the dB figure from?
These figures include the dBW value:
1000W Transmitter at 65Km
PDs = 1000.0
PDr = 0.000000018834904507916607783299854
dBW = -77.250365773078073927642982876853
1000 W Transmitter at 65.1Km...
A quick check with the calculator showed 3 Watts or 0.003%.
Yes, this is very broad, there should be no reason even with moderate hardware that this could be controlled to milliWatt level or 0.000003%. I would say that no source of error is ever insignificant as it will be compounded by...
Here's a calculator that shows you're wrong:
http://www.cdt21.com/resources/siryo3_01.asp
Enter 1000 for TX Power, 65000 for the distance and 0 for the gain. If you now look at the Power density Wr, it agrees with my figure at 1.8834905E-8.
Let's look at post #35...
Lets do the math and calculate the power density at 65Km (We will omit loss and interference for the moment):
Now the power density at 65.1Km:
and to determine the difference between 65.1Km and 65Km, or a 100m resolution, we need a power sensitivity of at least...
I didn't define the function f(PDs) to prevent compound errors for nothing. Have you been reading this thread at all?
Again, we already defined this:
PDr = (PDs /4 pi R^2) - ASL
If you had been following the discussion, we were talking about trilateration of a signal anywhere on the...
What more do you need than trilateration of a spread spectrum signal in the sub-1000Hz range?
Two questions:
1. What are the potential sources of loss?
2. What is the expected accuracy?
Stop making up your own questions.
As I said before, I'm not really interested in your opinion of feasibility. Let's face it, you would not be posting here everyday if you were busy working in this field.
Also, you have made about 13 posts on this thread and not one of them contain any technical data to support your...
