Wildlife telemetry research has expanded greatly in the last 2 decades, with the application of satellite tracking and archival logging technologies to study the ecology and conservation of marine mammals, birds, fishes, and turtles. Widespread and expanding use of satellite tracking to study movements and habitats of marine megavertebrates warrants a review of progress to date and a discussion...

Designing a robust tracking control for a non-linear MIMO system with uncertainty is one of the most complicated control problems. In this paper, sliding mode changed to non-linear controllable canonical form by input-output linearization. This, sliding surfaces can be defined in a way that we can de-couple equations and indicate the sliding conditions of multi-variable controller system. The u...

This paper presents a novel electrical polarization tracking method for mobile satellite communication systems that use linear polarization. It consists of two main technologies; the first estimates the mobile station antenna’s relative polarization angle against that of the satellite’s onboard antenna, the second forms counter polarization against the estimated value. We use a Ku-band communic...

This paper proposes a nonlinear adaptive position and attitude tracking controller for satellite proximity operations between a target and a chaser satellite. The controller requires no information about the mass and inertia matrix of the chaser satellite, and takes into account the gravitational acceleration, the gravity-gradient torque, the perturbing acceleration due to Earth’s oblateness, a...

We present an approach for tracking water courses in satellite images, a general strategy for tracking and recognising features in computer vision tasks on satellite images. Our approach is related to recent work in automatic image interpretation and urban scene analysis. We report a method for image recognition from multi-spectral SPOT satellite imagery, based on the different response of wate...

Tracking and monitoring ocean features which have short coherent time periods from sequential satellite images requires that the images have both very high spatial resolutions and short temporal sampling intervals (i.e., repeated cycles). Satellite images from a single sensor in a polar-orbiting satellite usually cannot meet these requirements since high spatial resolution of the sensor may res...
