(Note that due to recent changes to the Heavens Above website, future support for this source may be discontinued).

Do not use this template on articles for spacecraft which are not currently in Earth orbit. Please read the instructions fully before setting up automatic updates. Consider discussing updates on the article's talk page or at the WikiProject talk page beforehand to ensure AstRoBot is suitable for that article.

Usage

Before using this template, it is recommended that you begin a discussion on the article's talk page and determine whether there is a consensus for that article to contain automatically updated orbital elements.

• {{Orbit|<parameter name>|<initial value>}} to display a parameter in the article
• {{Orbit|<parameter name>|<initial value>|hide}} for a control parameter which is not displayed

Two control parameters; epoch and satcat are required for the bot to retrieve data. It is strongly recommended that they be displayed in the article, however the hide parameter is available if it is needed.

The template can be nested inside others, such as साँचा:tl for the apogee, perigee, altitude at epoch and semi-major axis:

• {{Convert|{{Orbit|<parameter name>|<initial value>}}|km|mi}}

Use of this template for spacecraft outside Earth orbit is not recommended.

Supported parameters

Data	Parameter name	Infobox field	Units	Remarks
Argument of perigee	arg of perigee	orbit_arg_periapsis	degrees
Apogee	apogee	orbit_apoapsis	kilometres
Altitude at epoch	altitude at epoch	(none)	kilometres
Eccentricity	eccentricity	orbit_eccentricity	dimensionless
Epoch date	epoch	orbit_epoch	n/a (date)	required
Epoch time	epoch time	included in orbit_epoch	n/a (time)	Include, along with epoch, for greater precision
Inclination	inclination	orbit_inclination	degrees
Mean anomaly	mean anomaly	orbit_mean_anomaly	degrees
True anomaly	true anomaly	(none)	degrees
Eccentric anomaly	eccentric anomaly	(none)	degrees
Number of orbits completed	orbits	orbits_completed orbit_rev_number	dimensionless	Updates two infobox fields - orbits_completed is intended as a total over the spacecraft's lifetime, while rev_number is specific to the displayed elset. From the bot's perspective, using the most up-to-date information, they are identical
Perigee	perigee	periapsis	kilometres
Right ascension of the ascending node	RAAN	orbit_RAAN	degrees
Speed at epoch	speed at epoch	n/a	kilometres per second	Not suitable for eccentric orbits
Average Speed	average speed	orbit_velocity	kilometres per second
Mean motion	mean motion	orbit_mean_motion	dimensionless	Given in orbits per day
Orbital period	period	orbit_period	minutes
Semi-major axis	semimajor axis	orbit_semimajor	kilometres
Citation	ref	(none)	n/a (string)	Provides a reference to the page the orbital elements were obtained from. Must only include a reference, wrapped in <ref> tags
Satellite Catalog Number	satcat	SATCAT	n/a (string)	Required, not updated (constant) - used to identify satellite
Data source	datasource	n/a	n/a	HN, NH, H or N Specifies whether the bot uses Heavens-Above (H) or n2yo (N) for orbit data, and if both are selected the order of preference. Defaults to NH (n2yo then heavens-above)
