Title: The Innovative Contributions of Robert Fischer

Introduction

Robert Fischer is a notable inventor based in Houston, TX (US). He has made significant contributions to the field of seismic surveying, particularly in icy waters. His innovative approach addresses challenges faced in obtaining accurate GPS readings during seismic surveys.

Latest Patents

Fischer holds a patent for "Declination compensation for seismic survey." This invention is crucial for conducting seismic surveys in icy waters, where traditional methods may fail. In this method, streamers are towed behind a vessel under the water's surface to avoid ice interference. The challenge arises when GPS readings cannot be consistently obtained due to the ice preventing a tail buoy with a GPS receiver from trailing from the streamer at the surface. Fischer's solution involves a device that tows on the streamer under the water's surface. The streamer's absolute position is tracked by intermittently bringing the towed device toward the surface to obtain GPS readings. This absolute position can then be correlated with compass readings, allowing for accurate seismic sensor signals obtained along the streamer during the survey. The compass readings can be corrected for declination using declinometer readings, which can also compensate for iron effects from the vessel or other devices carrying the declinometer.
