Coincidence Search Engine (csengine)
This is the callable interface to the Coincidence Search Engine which may be used to search for times when up to four satellites were over or within the same geographic area simultaneously. Searches may be constrained by time, geographic area, and/or distance between the satellites' nadirs. The output consists of a sequence of text lines listing the date, time, satellite name, and latitude and longitude.
Due to NASA security restrictions, the service is unable to provide coincidence predictions; only historical events may be calculated.

Satellite Services (satellites)
This service provides two functions: Two-line elements server and satellites server.
The caller can use a REST interface to retrieve the latest TLE using the "elements" interface by providing a satellite id (number) or a satellite name (string), a from date, and a thru date. The interface will return the latest TLE that is on or before the start date. Note that this information is gathered from our local copy of TLEs which we download regularly from Space-Track for a select list of satellites. It will not provide TLEs for satellites we do not "track".
The caller can use a REST interface to retrieve the satellite information using the "satellites" interface by providing a satellite id (number) or a satellite name (string). This service returns information about the satellite that we store locally, including the satellite's orbital period and the satellite's nominal altitude. It will also translate the name to the satellite id and vice-versa.

Storms (storms)
This service provides information about tropical storms for Atlantic, and Eastern and Central Pacific storms. We gather these data from the HURDAT files annually and also update the database with information provided by NHC during storm season. Two services are provided, one to retrieve storm information and one to retrieve track information for a specific storm.
The caller can use a REST interface to retrieve information about storms using the "storms" interface. There are a number of optional parameters that can be provided to narrow the search by name (possibly wildcarded), from/thru date, area-of-interest bounding box, min/max pressure, min/max wind speeds, min/max category, and basin (Atlantic or Pacific). The result is XML containing a list of storms with specific values for all of the parameters.
The caller can use a REST interface to retrieve track information for a specific storm by providing the storm name and year or the stormid. The result is XML containing information about the specific storm and a list of the track information.
