Three innovative features to complement standard GPS functions

ASTROTRACER

The O-GPS2 calculates the movement of celestial bodies using the latitude obtained from the location data and the camera's alignment data (horizontal and vertical inclinations}detected by the electronic compassand 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.

Simple Navigation

This function linearly navigates you to a desired location by calculating the direction and distance from the current position to the destination

Electronic Compass

This function accurately displays the camera's direction at the time of shooting on the camera's LCD monitor.

ASTROTRACER

For effortless tracing of celestial bodies

When mounted on the supported PENTAX cameras, the O-GPS2 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 the location data and the camera's alignment data (horizontal and vertical inclinations and direction) obtained from the electronic compass and acceleration sensors. It then shitts 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.

Sample applications of Simple Navigation

Input a desired destination using location data stored on recorded images or GPS location data obtained from social network websites. This function provides you with linear navigation from the current position to the destination, based on the obtained GPS location data.

Select a destination from preset points.

Select a destination from GPS data stored on recorded images.

Select a destination from location data files created on your PC.

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 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.


Destination setup file

How to save and back up destination setup files

The O-GPS2 lets you register up to 40 locations as potential destinations. You can also save them as a "destination setup file" and save the file on an SD memory card as backup data. You can save up to three destination setup files on a single SD memory card, meaning that a total of 120 locations (40 locations x 3 files) can be stored on the card. When saving these files, simply follow the instructions presented on the Simple Navigation destination management screen.

[Example] When "GPSDATA_01" is assigned as a saved file title on an SD memory card.

How to read in destination setup files

You can read destination setup files (up to three files) stored on an SD memory card into your camera. When reading in these files, simply follow the instructions presented on the Simple Navigation destination management screen. Since only one file (with a maximum of 40 locations) can be read into the camera in a single operational sequence, you must repeat the sequence again to read in other files.

[Example] When files "My_select_01" to "My_select_03" are saved on an SD memory card.

Note

If an SD memory card is reformatted, destination setup files stored on it are automatically erased. To avoid accidental loss of such files, we suggest that you copy these files onto your computer as a backup.


Original destination setup files

You can also create your original destination setup files on the computer and read them into the camera.

How to create files

1. Destination setup file

You can read a destination setup file stored on an SD memory card into the camera. In this case, you may use three text files titled "GPS_DAT*.TXT" (* = 1, 2 or 3). Files with other titles cannot be read into the camera. To construct a destination setup file, you must follow the diagram at right. The numeral * of a DATA * folder must be identical with the numeral * of a GPS_DAT*.TXT file.

 

•When a destination setup file is read in from an SD memory card, the camera's existing destination setup data is automatically overwritten with the new read-in data while the existing data is erased.

•When saving the camera's destination setup data onto an SD memory card, the existing data on the selected DATA* folder is overwritten with the new data while the existing data is erased.

•With the PENTAX 645D, the SD2 slot must be used for saving and reading in the destination setup data.

2. File size

The maximum volume of a destination setup file is 32KB (32,768 bits).

Note: When the data volume of a file exceeds 32KB, the excess data cannot be saved.

3. Maximum number of destinations to be registered

A maximum of 40 destinations can be registered in a single file.

4. Letters, numbers and symbols available for destination setup file title

Only one-bit letters, numerals and symbols can be used for destination setup file titles.

Note: * indicates a space.

5. Storable data

A file title and destination data (names, latitudes and longitudes of destinations) can be stored in each file, and displayed on the camera's LCD monitor.

A file title is described in TITLE=title contents format.

Destinations data is described in DATA=destination, latitude, longitude format.

A maximum of 40 destinations can be stored in a single file.

For actual data description steps, refer to 6. File setup sample below.

GPS-guided compass to assure accurate pointing of true north

The O-GPS2's Electronic Compass is not only useful in all types of outdoor activities, but it is also extremely dependable in astronomical photography, since it tells you true north regardless.

The O-GPS2 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                  

Calibration

Before each use, the O-GPS2 must be calibrated for optimum results

What is calibration?

Calibration is a means of properly adjusting the O-GPS2's setup so the GPS unit can obtain accurate location data. The O-GPS2 must be calibrated before shooting images which needs direction information such as Astrotracer. There are two types of calibration: simple calibration for general use, and "high-precision calibration" for the ASTROTRACER function.

How to calibrate?

Calibration

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

 

    

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.

 

    

Notes

* Calibration does not require turning the camera in a circular motion while changing hands.

* 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-GPS2'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-GPS2 may not point in the proper direction when calibration is completed. The same may result when the O-GPS2 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-GPS2 may not point in the proper direction when calibration is completed.

* When the lens or LCD monitor's angle is changed after calibration/high-precision calibration is completed, the environmental magnetism may be affected and may not point in the proper direction.

* Calibration/high-precision calibration and shooting are recommended when LCD monitor is stored.
