How do I ungzip a string like this

I have this string:
H4sIAAAAAAAA/6VRPQvCMBD9K+VmBxF0yNZV6KLiIiJnc4RgPkqSilL6371o0Yo4iFNy79679y7p4Gh8fYogdh1oCeJRw2Q4BdCZXOIag2IWkxLZTN/3jNVJe8ekpdcO+smXEY3BK4XDwP4c9bjdkSxPl+wnMWGGHFpisA3WW+jZNBqfQEzvbmPZ0RwSqpHSN0O6UsoiNlhT5G7mCNjQJRVbNC0VFQWlXRY+11mTkxXFiIq+rvGKMpv/kGVFqjUYnkFKo5Wz/MRF5SX9EWLRv/3IWM2dG7pEKD7oAQAA
And I want to decompress it using gzip.
I spent almost 2 hours on this now and can't seem to find out how to do this.
Does anyone know? I am new to Kotlin and I've never done that before.
Use java.util.Base64 to convert the Base-64 to binary. Then ungzip that.

Can you help me with this simple RobotC exercise?

I mean 2. Second Length found here
I think I found all mistakes but still, I can't seem to get the right answer.
On line 8 it should be wait1Msec(3000); instead of wait1Msec(4000);
Swing turn to the right should be written as 100 power for C and 0 power for B. I also tried -100 for B and even exchanged letters just in case I misunderstood which of the motors is left and which is right, but I still got the wrong answer (according to the website).
There are mistakes in the comments as well, but that shouldn't be a problem since they're just comments! Still, I corrected them just in case. Replaced 4 with 3 and replaced right with left, still not correct.
Do they expect me to right some specific text in the comments? Or am I missing something?
It seems that you should write the code for your second length after the comment
//END OF FIRST LENGTH
So, your code should be a code for the first length and the second length. I hope that helps.

How to calculate satellite position using ephemerides data

I got a problem regarding ephemerides data.
The description of the ephemerides data is located here:
http://www.navcen.uscg.gov/pubs/gps/sigspec/gpssps1.pdf
I can extract the bits/bytes that are important. I just don't know how to interprete them.
It seems there is no information about that. I guess from the document that it should contain Keplerian data to calculate the position of a satellite in "WGS-84 Earth-Centered Earth-Fixed" format, which is what I need.
This document says that I can calculate the final position "utilizing a variation of the equations shown in Table 2-15"
The parameters that I need to fill into this terms are
Cus Cuc Crc Crs Cic Cis IDOT toe io
I know how long these parameters are, but not where to start to read them inside of the datastream
Looking at page 32, I see that they are there, but where they are inside of this block of "words", thats a secret for me.
Can anyone help ?
I dont ask anyone to read the whole pdf, thats a bit too much, but maybe someone has a deep knowledge regarding this topic already.
And this terms are a bit confusing, because some of them are defined recursive
A = sqrt(A^2)
vk = something * Ek
Ek = something * vk
Thanks in advance
I'm currently working on similar problems. So far the opensource library gnss-sdr has been of great help. Especially src/core/system_parametes/gps_navigation_message.cc where the function
int Gps_Navigation_Message::subframe_decoder(char *subframe)
which decodes and stores each subframe is defined.

Skroll issue with multiple relative keyframes

I'm using Skrollr and trying to set multiple relative keyframes. This doesn't work for me at the moment.
data-bottom-top="opacity:0;transform:translate3d(100%,0,0)" data-top-top="opacity:1;transform:translate3d(0,0,0)" data-top-botttom="transform:translate3d(0,50%,0) data-100p-top-botttom="transform:translate3d(0,50%,0)"
Have been cracking my head over this for the past few days. Any help would be greatly appreciated!
Just to answer the question fully, you must use the same units for each argument:
data-bottom-top="opacity:0;transform:translate3d(100%,0%,0)"
data-top-top="opacity:1;transform:translate3d(0%,0%,0)"
data-top-botttom="transform:translate3d(0%,50%,0)
data-100p-top-botttom="transform:translate3d(0%,50%,0)"

Microsoft Text Encodings

Have a string being returned from a modem as such;
TÁÎË ÐROÄÕCT ÖOLÕÍE TC ÖOLÕÍE ÕLLÁÇE ÈEIÇÈT WÁTER TEÍÐ
When I save the text to a document and open it in Word I am able to decode it using the "US-ASCII" encoding and get the follwing text.
TANK PRODUCT VOLUME TC VOLUME ULLAGE HEIGHT WATER TEMP
However for the life of me I cannot figure out how to acheive the same results in vb. Am using Visual Basic Express 2010.
If anyone could help I would greatly appreciate it.
Thanks
Thanks for the help. Turns out it wasn't an encoding issue as you all pointed out but rather the word length and parity both needed to be adjusted. Final settings on the modem ended up being 9600-7-Odd-1.
