find_satellites_above

List satellites above an observer within an angular search radius.

Signature: find_satellites_above(observer_lat: decimal number, decimal degrees (WGS84), required; observer_lon: decimal number, decimal degrees (WGS84), required; observer_alt_m: decimal number, metres, optional, default 0; radius_deg: integer, degrees, optional, default 30; category_id: integer, optional, default 0; limit: integer, items, optional, default 25; offset: integer, items, optional, default 0)

Direct GET

For navigating agents: open the HTML page with parameters in the URL. The result is fetched and displayed without screenshots or form filling.

Open this validated HTML GET URL

https://allemannsdata.com/wiki/kilder/n2yo/find_satellites_above/?observer_lat={observer_lat}&observer_lon={observer_lon}&observer_alt_m=0&radius_deg=30&category_id=0&limit=25&offset=0

Replace {observer_lat}, {observer_lon}, {observer_alt_m}, {radius_deg}, {category_id} with values. Remove unused optional parameters from the URL.

For software and dashboards: Read the operation descriptor. The JSON GET template is https://allemannsdata.com/wiki/api/v1/kilder/n2yo/find_satellites_above?observer_lat={observer_lat}&observer_lon={observer_lon}&observer_alt_m=0&radius_deg=30&category_id=0&limit=25&offset=0. Open this exact request as JSON.

Parameter	Requirement	JSON type	Description
`observer_lat`	required	number	Observer latitude in WGS84 decimal degrees. Unit: decimal degrees (WGS84).
`observer_lon`	required	number	Observer longitude in WGS84 decimal degrees. Unit: decimal degrees (WGS84).
`observer_alt_m`	optional	number	Observer altitude above sea level in metres. Unit: metres.
`radius_deg`	optional	integer	Search radius from 0 to 90 degrees. Unit: degrees.
`category_id`	optional	integer	N2YO category id; 0 means all categories, 1 brightest.
`limit`	optional	integer	Gateway page size; default 25, maximum 100.
`offset`	optional	integer	Number of list items to skip; default 0.

Generated JavaScript, Python and response structure

Use JSON when the user requests code, machine-readable data, value extraction or further computation. Use the HTML GET page to identify the correct source and verify parameters.

Example for generated JavaScript and Python

https://allemannsdata.com/wiki/api/v1/kilder/n2yo/find_satellites_above?observer_lat={observer_lat}&observer_lon={observer_lon}&observer_alt_m=0&radius_deg=30&category_id=0&limit=25&offset=0

Replace URL placeholders and remove unused optional parameters.

JavaScript in a dashboard

const url = "https://allemannsdata.com/wiki/api/v1/kilder/n2yo/find_satellites_above?observer_lat={observer_lat}&observer_lon={observer_lon}&observer_alt_m=0&radius_deg=30&category_id=0&limit=25&offset=0";
const response = await fetch(url);
if (!response.ok) {
  const failure = await response.json();
  throw new Error(`${failure.error.code}: ${failure.error.message} ${failure.suggestion}`);
}
const result = await response.json();
const data = result.data;

Python without additional packages

import json
from urllib.request import urlopen

url = "https://allemannsdata.com/wiki/api/v1/kilder/n2yo/find_satellites_above?observer_lat={observer_lat}&observer_lon={observer_lon}&observer_alt_m=0&radius_deg=30&category_id=0&limit=25&offset=0"
with urlopen(url) as response:
    result = json.load(response)
data = result["data"]

Response structure

How an AI agent should use this page

Ground rule: Navigate with HTML GET links to keep explanations and relationships. Use the page's JSON alternative only when concrete values must be extracted, compared or computed.

How to use the find_satellites_above lookup

Replace the placeholders in the HTML GET template; remove optional parameters you do not need.
Check types, units, limits and ID formats in the parameter table.
Follow linked results to canonical pages before combining sources.

Misreading to avoid: An empty list means "no results for this lookup". An error message or unavailable source does not mean the data does not exist.

Source-specific next step

State the NORAD ID, observer coordinate, altitude and time window. A pass is observer-dependent.

Go to the source page for other operations. Use the JSON template only after the HTML result shows that the parameters and source are correct.
