Simply by mounting the O-GPS1 onto the hotshoe of a PENTAX digital SLR camera,* the user 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 PC. GPS location data stored on such files also makes it much easier to sort and file recorded images.

By coupling GPS data with the camera’s SR (Shake Reduction) system, the unit offers a range of unique, advanced applications, including ASTROTRACER, Simple Navigation and Electronic Compass.

GPS function for effortless recording of shooting location data

The O-GPS1 mounts on the hotshoe of a compatible camera and records the latitude, longitude, altitude, universal time coordinated (UTC) and direction of the shooting location onto captured images. Using mapping software such as Google Earth™, the user can easily recall shooting locations and directions on a map. This function is very helpful later in sorting and filing the recorded images.

Note: When the O-GPS1 is used in locations where it cannot receive signals from GPS satellites, location data may be in error or missing.

ASTROTRACER for effortless astronomical photography

When mounted on the PENTAX K-5 or K-r camera body, the O-GPS1 also offers the advanced ASTROTRACER function,** which couples the unit with the camera’s SR (Shake Reduction) system for the effortless tracking and photographing of celestial bodies. The unit calculates the movement of stars, planets, and other bodies using the latitude obtained from GPS data and the camera’s alignment data (horizontal and vertical inclinations and aspect) obtained from its magnetic and acceleration sensors, then shifts the camera’s image sensor in synchronization with the movement of the objects.*** As the result, stars and other bodies are captured as solid points rather than blurry streaks, even during extended exposures. It also makes astronomical photography much simpler, as it requires only a tripod and eliminates the need for an additional accessory such as an equatorial telescope.

** This function is available only when the O-GPS1 is mounted on a PENTAX digital SLR camera body equipped with a magnet-driven SR system.

*** The duration of ASTROTRACER operation may vary depending on photographic conditions.

Simple Navigation to indicate location data to a destination

The O-GPS1 offers a Simple Navigation function, which calculates the direction and distance to a given destination from the current position. The user can either locate destinations using location data stored on recorded images, or register and/or assign them by uploading location data created on a PC.****
**** At the time of purchase, the O-GPS1 has nine PENTAX international service centres as pre-set destinations.

Electronic Compass function to indicate and record direction

The O-GPS1 comes equipped with an Electronic Compass function, which displays the camera’s direction on its LCD monitor with great precision. Using the aspect of geomagnetism detected by its magnetic sensor and GPS location data, the unit indicates the aspect in relation to true north. The user can also record directional data on captured images.

Other features

• Simplified weather-resistant construction for use in light rain
• Independent power source (one AAA-size battery) to eliminate the need for power supply from the camera body
