My overall recommendation is to look at the tables in the ideal calculator thread for each scanner, and find an altitude and inclination combo which (within error) appears for all three types of scanners. There are three types of maps to get science credit from: LowRes Altimetery (from RADAR), HiRes Altimetery (from SAR), and Biome (from Multi). If you are somewhere between 30% and 95%, you get partial credit. If you have more than 95% of a particular map revealed, you get all science points available. If you have less than 30% of a particular map revealed, you get no science points. Now, as for science: this is relatively simple. Tl dr each scanner has different properties, so running all four of them on the same satellite with an arbitrary orbit will not be optimal, but the Multi and RADAR scanners are very similar They are also listed in the file scanners.txt (see the last page of the ideal calculator thread). If you are above this altitude (but below the maximum) there is a quadratic bonus.Īll of these properties are listed in the ideal altitude tables that the calculator spits out. If you are below this altitude, there is a linear penalty (removed from the FOV) down to the minimum altitude (which is 5 km for all scanners). Each scanner also has a best altitude (hand-picked, by the original author of SCANsat). (The SAR works up to 800 km, while the others will stop working at 500 km). The RADAR scanner has the highest (of 5 degrees), and the Multi is in between (4 degrees). The SAR (high resolution altimetry) scanner has the smallest FOV (of 2 degrees). Of note, each scanner has a different field of view. Unlike an equatorial orbit, a polar (90 degree) orbit has a chance of scanning a whole planet because the planet rotates underneath the scanner.Īlso, each scanner has different properties. This should be pretty easy to understand, since doesn't really vary much in latitude.Ī polar orbit is another extreme. In general, an equatorial (0 degree) orbit will only scan a tiny amount of a planetary body. I am the maintainer of the SCANsat add-on as well as the ideal altitude calculator which tells us, for each scanner, which orbits take how long to complete the scan.
