Electronic Compass function assists while hiking or camping.

Chart the progress of a hike, bike, or boating trip with interval position tracking.

Supports terrestrial-based WAAS for highly accurate positioning.


Features:Featuring convenient, simple-to-use equatorial telescope functions, the O-GPS1 allows easy filing of recorded images using location data such as a shooting location and the camera's direction, and opens up new dimensions in digital photography.

 

 

Simply by mounting the O-GPS1 accessory GPS unit onto the hotshoe of a PENTAX digital SLR camera, you can record the latitude, longitude, altitude, universal time coordinated (UTC) and aspect of shooting locations onto captured images. Image files carrying GPS location data can be used to track shooting locations and review location data on a computer. The GPS location data stored on these files also makes it much easier to sort and file recorded images. By coupling GPS location data with the camera's SR (Shake Reduction) system, this GPS unit offers a range of innovative, PENTAX-original applications, including ASTROTRACER, Simple Navigation and Electronic Compass.

Three innovative features to complement standard GPS functions

ASTROTRACER

ASTROTRACER
PENTAX-original simplified equatorial telescope function using the camera's SR system

The O-GPS1 calculates the movement of celestial bodies using the latitude obtained from GPS location data and the camera's alignment data (horizontal and vertical inclinations) detected by the unit's magnetic and acceleration sensors. It then shifts the camera's image sensor in synchronization with the movement of the objects. This means that stars and other bodies are captured as solid points rather than blurry streaks, even during extended exposures.

For effortless tracing of celestial bodies

When mounted on the PENTAX K-5 or K-r camera body, the O-GPS1 provides the advanced ASTROTRACER function, which couples the unit with the camera's SR (Shake Reduction) system for the effortless tracing and photographing of celestial bodies. The unit calculates the movement of stars and other objects using the latitude obtained from GPS data and the camera's alignment data (horizontal and vertical inclinations and direction) obtained from the unit's magnetic and acceleration sensors. It then shifts the camera's image sensor in synchronization with the movement of these objects. This means that all celestial bodies are captured as solid points rather than blurry streaks, even during extended exposures. It also simplifies the astronomical photography setup, since it requires only a tripod and eliminates the need for an additional accessory such as an equatorial telescope.

Linear Navigation To Destination

This user-friendly function calculates the direction and distance to a given destination from the current position. You can either locate destinations using location data stored on recorded images, or register and/or assign them by uploading location data created on your PC.Note: At the time of purchase, the O-GPS1 has nine PENTAX international service centers stored as preset destinations.

Simple Navigation

Sample applications of Simple Navigation

    detail

By sharing detailed data of shooting locations (including the camera's direction) from image files exchanged on the Internet or via e-mails, you can develop a totally new photographic communication network where you can easily and quickly move to desired shooting locations with the guidance of a navigation system.
This function is perfect for active outdoor photographers, as it not only simplifies the sorting and filing of their own images, but it also lets them easily plan exciting, interesting events, such as an orienteering competition using only photographic data as a clue, or a relaxed traveling shooting session without the need for a PC or smartphone.


ELECTRONIC COMPASS : DISPLAY & RECORD CAMERA'S DIRECTION DURING SHOOTING

The O-GPS1's Electronic Compass function displays the camera's precise direction at the time of shooting on the camera's LCD monitor. Using the aspect of geomagnetism detected by the GPS unit's magnetic sensor and GPS location data, the unit indicates the aspect in relation to true north. You can also record directional data on captured images.

GPS-guided compass to assure accurate pointing of true north

 

 

 

The O-GPS1 points true north with unfailing accuracy by compensating the direction of geomagnetism detected by the built-in magnetic sensor with the magnetic variation of a given spot calculated using GPS location data.



Calibration : Before each use, the O-GPS1 must be calibrated for optimum results.

What is calibration?

Calibration is a means of properly adjusting the O-GPS1's setup so the GPS unit can obtain accurate location data. The O-GPS1 must be calibrated before each use.
There are two types of calibration: simple calibration for general use, and "high-precision calibration" for the ASTROTRACER function.

How to calibrate

Recall the calibration screen from the camera's main menu.
Rotate the camera at least 180 degrees in three directions, as illustrated above.
When the O-GPS1 is successfully calibrated, the letters "OK" will appear on the camera's LCD monitor.

Calibration for general use

Recall the calibration screen from the camera's main menu, and move the camera as instructed in the illustration and video above.

Rotate the camera at least 180¡ë in each direction.

High-precision calibration for ASTROTRACER function

Recall the high-precision calibration screen from the camera's main menu, and move the camera as shown in the illustration and video above.

High-precision calibration : Rotate the camera at least 180¡ë in each direction.

High-precision calibration : Completed

Notes

  • * Do not swing or twirl the camera while changing your grip on it.
  • * When calibration is unsuccessful, face in a different direction and/or slightly change the angle of grip, then try again.
  • * Calibration data is retained even when the O-GPS1's power is turned off.
  • * Calibration can be made regardless of GPS signal reception status.
  • * At locations that are strongly affected by environmental magnetism, it may be difficult to make a successful calibration, or the O-GPS1 may not point in the proper direction when calibration is completed. The same may result when the O-GPS1 is calibrated indoors.
  • * At locations affected by geomagnetism, such as in volcanic regions, it may be difficult to make a successful calibration, or the O-GPS1 may not point in the proper direction when calibration is completed.
