Transit (2012 film)

Transit is a 2012 American action-thriller film directed by Antonio Negret.

Plot

The film opens up with an armored truck coming across a car accident in the middle of a road. The driver finds this suspicious and prepares to drive off, but the truck is suddenly attacked by masked robbers. The driver tries to make a break for it, but his partner is revealed to be in on the heist. They execute the driver when an alarm in the truck goes off, and then his partner when he questions the lead robber's motives.

After the heist, local law enforcement have created road blocks in search of the robbers. The four robbers, Marek, his girlfriend Arielle, Losada, and getaway driver Evers know that they fit the profile of the robbers and so, to prevent themselves from being caught, hide the $4 million in a tent bag belonging to a family of four who are on a camping trip. They manage to hide the bag full of money in the family's camping gear on top of their Land Rover while the family uses restrooms at a small gas station.

Transit (satellite)

The TRANSIT system, also known as NAVSAT or NNSS (for Navy Navigation Satellite System), was the first satellite navigation system to be used operationally. The system was primarily used by the U.S. Navy to provide accurate location information to its Polaris ballistic missile submarines, and it was also used as a navigation system by the Navy's surface ships, as well as for hydrographic survey and geodetic surveying. Transit provided continuous navigation satellite service from 1964, initially for Polaris submarines and later for civilian use as well.

History

The TRANSIT satellite system sponsored by the Navy and developed jointly by DARPA and the Johns Hopkins Applied Physics Laboratory, under the leadership of Dr. Richard Kirschner at Johns Hopkins was the first satellite positioning system. Just days after the Soviet launch of Sputnik 1, the first man-made earth-orbiting satellite on October 4, 1957, two physicists at APL, William Guier and George Weiffenbach, found themselves in discussion about the microwave signals that would likely be emanating from the satellite. They were able to determine Sputnik's orbit by analyzing the Doppler shift of its radio signals during a single pass. Discussing the way forward for their research, their director Frank McClure, the chairman of APL's Research Center, suggested in March 1958 that if the satellite's position were known and predictable, the Doppler shift could be used to locate a receiver on Earth, and proposed a satellite system to implement this principle.

Theodolite

A theodolite /θiːˈɒdəlaɪt/ is a precision instrument for measuring angles in the horizontal and vertical planes. Theodolites are used mainly for surveying applications, and have been adapted for specialized purposes in fields like meteorology and rocket launch technology. A modern theodolite consists of a movable telescope mounted within two perpendicular axes—the horizontal or trunnion axis, and the vertical axis. When the telescope is pointed at a target object, the angle of each of these axes can be measured with great precision, typically to seconds of arc.

Theodolites may be either transit or non-transit. Transit theodolites (or just "transits") are those in which the telescope can be inverted in the vertical plane, whereas the rotation in the same plane is restricted to a semi-circle for non-transit theodolites. Some types of transit theodolites do not allow the measurement of vertical angles.

The builder's level is sometimes mistaken for a transit theodolite, but it measures neither horizontal nor vertical angles. It uses a spirit level to set a telescope level to define a line of sight along a horizontal plane.
