DMagic Posted January 19, 2015 Author Share Posted January 19, 2015 Just use the equatorial crossing lines on the orbit overlay to judge scanning coverage. If the crossing lines start to bunch up or overlap entirely then you are in a bad orbit. Very small changes in orbit can lead to big changes in scanning coverage, so it usually only takes a little bit of dV to get into a good orbit.

I've actually just been sitting there with probes at different altitudes and inclinations testing it out. Just seemed odd to me that in a thread about ideal orbits a fair few of them are at such low inclinations that they can't possibly scan the entire surface. Just wondered if maybe the FOV had changed or something, or maybe nobody questioned it before. Quote Link to comment Share on other sites More sharing options...
C.A.Sizemore Posted January 20, 2015 Share Posted January 20, 2015 I am having two issues, Nothing happens when I use the big maps button and I can not retrieve any science from my satellites. I am going to reinstall the .dll and reboot. Both have radios and power to spare. Quote Link to comment Share on other sites More sharing options...
Pecan Posted January 20, 2015 Share Posted January 20, 2015 You could just do a 90 degree or maybe 85 degree orbit, that'll guarantee getting all of it, even if it just takes longer.*has no clue what the best orbits are supposed to be anyway*..."Best" orbits are those that scan the whole surface as quickly as possible.Thought 1: Low orbits are better because the orbital period is shorter (more laps per hour).Thought 2: High orbits are better because the FOV (Field Of View) covers a wider strip on each orbit.Thought 3: If the orbital-period matches the rotational period of the body (eg; Kerbin-stationary orbit altitude) you'll go over the same strip every time.Thought 4: If the orbital-period is a twice, or or three-times, (or half or a third) etc. of the body's rotation you have a 'resonant' orbit, which will only ever cover the same two, or three, etc. strips.So it isn't quite as simple as always using the same altitudes (but it generally isn't too bad either, as DMagic said).

DBT85 Posted January 20, 2015 Share Posted January 20, 2015 That's what I didn't understand from the orbits in that thread. Many simply don't work despite saying they are capable of a full scan in x hours. Some are great, but lots aren't. Just seemed weird to me.

I haven't looked at that thread for ages so had no answer for you; just a quick recap for those that don't know what you're talking about (and smjjames won't be the only one or the last one).

Mulbin Posted January 21, 2015 Share Posted January 21, 2015 Can anyone help me out... I'm trying to add the scansat module to some stock parts but I just can't get it to work!I've created a module manager file with...@PART[mediumDishAntenna]{ MODULE { name = SCANsat sensorType = 2 //2^1 fov = 2 min_alt = 5000 max_alt = 800000 best_alt = 750000 power = 1 scanName = SAR Scan animationName = Deploy }{... but I have no option in the gui to start the scan. What am I missing? I can't see anything else in the part configs for the scansat parts. Quote Link to comment Share on other sites More sharing options...
Splendid1 Posted January 21, 2015 Share Posted January 21, 2015 Hello guys.I just got SCANsat, and have set up 3 satellites in polar orbits with inclinations of perfect 90deg (100km alt.) around Kerbin, Mun and Minmus with all Scansat equipment. Kerbin reads 100% while Minmus and the Mun only read 90.0% each. Why is this? what is the other 10% and why am I not getting it? Thanks for any answers.

Mynar Moonshadow Posted January 21, 2015 Share Posted January 21, 2015 Personally I use an inclination of 87.5-ish for them. When you look at the map, change the map type and look for any blank spots. When you mouse over an area that is unscanned, it won't show a biome name. Typically I miss the polar regions a little bit when messing around with inclination settings.For reference, I found http://forum.kerbalspaceprogram.com/threads/75854-0-24-x-Ideal-SCANsat-Altitudes-v1-0-Aug-16 useful to get started. However I don't necessarily agree with some of the recommendations it suggests, I mostly use trial and error method with a satellite.

I can see everything for all 3 plantoids, so Why is minmus and Mun only 90%? shouldn't they be a hundred. Quote Link to comment Share on other sites More sharing options...
Mynar Moonshadow Posted January 21, 2015 Share Posted January 21, 2015 You are missing sections for the scan.What I normally do is:Satellite with 4 scanners KA-100, MKS camera, and two SCANsat ... err .. can't think of the names offhand (multispectral and radar I think) ... 253K ALT, 87.5ish INC around mun ... and takes roughly 4days to scan 100%. It isn't optimal by any means, but it works. Quote Link to comment Share on other sites More sharing options...

Its possible your orbit is slightly resonant so it keeps missing the same section.And are you putting all three scanner on one vessel?I've only played with Radar Altimetry and Multispectral on one vessel.If you're using all three, turn them all off and turn on one and see what its percentage is, if 100% then turn it off and move to the next.

That is, they see a different width of the ground beneath them. Plus each body you're scanning is a different size. For those reasons, you can't use the same orbital height for different instruments and different planets/moons and expect to get the same coverage for all the instruments. Vary your orbital height. If you've got the poles covered well already, change your orbital inclination to 70º - 85º and get better coverage over the mid-latitudes. Etc. There is no "one size fits all" solution to orbital mapping coverage for every instrument and every planetary body/moon. Quote Link to comment Share on other sites More sharing options...
hakan Posted January 21, 2015 Share Posted January 21, 2015 There is no "one size fits all" solution to orbital mapping coverage for every instrument and every planetary body/moon.But it should be possible to calculate close-to-optimum combinations of FOV, height, inclination and orbital height, right?/me goes trawling some wiki pages on mathematics of orbital mechanics./me gives up and goes to ask Scott Manley Quote Link to comment Share on other sites More sharing options...
smjjames Posted January 21, 2015 Share Posted January 21, 2015 Especially since the high resolution radar works best at a height that is too high for the low res radar and multispectral. Quote Link to comment Share on other sites More sharing options...

If you WANT that, you're simply going to have to vary your orbit from time to time to get the missed areas. Kind of like in the real world.

DBT85 Posted January 21, 2015 Share Posted January 21, 2015 Getting a single orbit for lo res altimetry and multispectral is possible. I've done that on practically every body. Not used the SAR yet. Quote Link to comment Share on other sites More sharing options...

I will right-click the instrument and look at the "Ideal / Sub-Optimal" values to see whether I am too high or too low. Quote Link to comment Share on other sites More sharing options...
Splendid1 Posted January 22, 2015 Share Posted January 22, 2015 What does it mean when the HI/LO/MULTI/BTDT on the mini map is coloured blue, instead of Green and/or Orange? I've made separate satellites for each scanning devices and put them in their ideal orbital heights (250km and 750km) at 90deg inclination.

I've made separate satellites for each scanning devices and put them in their ideal orbital heights (250km and 750km) at 90deg inclination.I've seen it turn blue once also, but I forget what the issue was. There doesn't seem to be any mention anywhere about it.the documentation- - - Updated - - -I also have a question...Is there any reason for leaving a satellite up in orbit with scanning active once the body orbited as been 100% scanned? Does the BTDT scanner need it, or does it read from your scanned maps? Quote Link to comment Share on other sites More sharing options...
