International Space Station Pass Times
The international space station (ISS) is an orbital outpost circling high above out heads. Sometimes it’s overhead, but when? It depends on your location. Given a location on Earth (latitude, longitude, and altitude) this API will compute the next n number of times that the ISS will be overhead.
Overhead is defined as 10° in elevation for the observer. The times are computed in UTC and the length of time that the ISS is above 10° is in seconds.
This gives you enough information to compute pass times for up to several weeks, but beware! times are less and less accurate as you go into the future. This is because the orbit of the ISS decays unpredictably over time and because station controllers periodically move the station to higher and lower orbits for docking, re-boost, and debris avoidance.
The API returns a list of upcoming ISS passes for a particular location formatted as JSON.
As input it expects a latitude/longitude pair, altitude and how many results to return. All fields are required.
As output you get the same inputs back (for checking) and a time stamp when the API ran in addition to a success or failure message and a list of passes. Each pass has a duration in seconds and a rise time as a unix time stamp.
This API has 2 required input values and 2 optional ones.
|Inptut||Description||Query string||Valid Range||Units||Required?|
|Latitude||The latitude of the place to predict passes||
|Longitude||The longitude of the place to predict passes||
|Altitude||The altitude of the place to predict passes||
|Number||The number of passes to return||
Appending a callback request to the query string will return JSONP:
The values used to calculate the upcoming passes are returned in
request object. The
response is a list of the timestamp
or each pass along with the
duration in seconds.
