What is "horta"

Horta may refer to:

Horta is a minor Etruscan goddess of agriculture, horticulture, or placename. This is based on a conjecture that the personal name Hurtate- is based on a root name *Hurta and on a chance similarity with the Latin word hortus "garden".

The District of Horta was a district of the (Adjacent Islands, the former collective name for the Azores and Madeira), consisting of the dependent western islands of the Azores, located in the Atlantic Ocean. The district of Horta, not to be confused with the modern municipality of Horta, existed from 1836 until 1976 when it was abolished in favour of the autonomy charter of the 1975 Portuguese Constitution.

Horta is a station in the Barcelona metro network, served by L5, located under carrer de Lisboa, in the Horta-Guinardó district of Barcelona. It was opened in 1967, when an extension of the line into the neighbourhood of the same name from Vilapicina was opened.

The partially curved island-platform station has a ticket hall at either end, one with two accesses, the other with one.

Horta was the terminus before the line was extended in July 2010 towards Vall d'Hebron, meeting L3.

HORTA is an underground geographic positioning technology utilized in the mining industry and being considered for extraterrestrial space mining applications. The technology utilizes a gyroscope and an accelerometer, together called an inertial navigation system or INS, to aid in 3D-position determination.

It was developed by Canadian mining company Inco in the late 1990s based on an earlier technology that had been originally developed for the U.S. military. It provides an automated solution to the problem of positioning and location in underground mines.

The term is a backronym for the Horta from Star Trek. As Inco uses the term, HORTA stands for Honeywell Ore Retrieval and Tunneling Aid.

A mining vehicle "with a HORTA mounted, can survey much faster and more accurately than manual surveys. It takes the truck 120 minutes to survey a 1.6-km-long drift, recording 1,500 points every 60 cm. This compares with a manual survey of the same distance that takes 180 hours, and records only five points every 6 m. Added benefits from such a detailed survey would be to allow engineers to design more effective ventilation systems, or to regularly check ground stability."

HORTA units may be fitted onto all mobile underground equipment, including drills, so their position may be determined with acceptable engineering accuracy.
