The first letter indicates the installation location and G stands for Ground Equipment (General) The next letter indicates the type of equipment and S means special or combination equipment. The third character indicates the items purpose but O is not listed as a valid character. In fact, I think O may be a typo since they usually avoid using O in reference designations to avoid confusion with the character 0 (zero). (Same with I and 1). The numbers should indicate the position of that item in the sequence of similar items but without knowing what O means then we can't guess at much other than the fact that there have been 220 items of a similar nature. Oh and it's most likely produced in the US. The US uses low numbers (0 to 500), Canada, the UK and other countries use higher range numbers (500 to 599 and 2200 to 2299 for Canada and UK, respectively). That's exactly right.

Part of this radio system is an AN/GSO-187. That will give you an idea of what the AN/GSO classification is used for. Joe
