Satellite telemetry was used to determine fall migratory movements of Ospreys (Pandion haliaetus) breeding in the United States. Study areas were established along the lower Columbia River between Oregon and Washington; in north-central Minnesota; on Shelter Island, New York; and in southern New Jersey. Seventy-four adults (25 males, 49 females) were tracked from 1995 through 1999. Migration ro...

The development of a space mission requires the implementation of several Test Equipments which simulate data flows for a specific payload. This paper describes a project involving the adoption of XML-related technologies in the management of those data flows arranged into telemetry packets. The project is mainly made up of three parts: the creation of an XML database containing the packet desc...

Long-term records of nesting numbers, or proxies to nesting numbers, show a precipitous decline in the size of many sea turtle populations. Population declines are most frequently attributed to fisheries bycatch, although direct quantification of this level of mortality is rare. We used satellite-tracking records for turtles in the Mediterranean Sea and Pacific, Atlantic and Indian Oceans to id...

This work describes a new hybrid method that combines information from processed satellite images with Artificial Neural Networks (ANNs) for predicting global horizontal irradiance (GHI) at temporal horizons of 30, 60, 90, and 120 min. The forecast model is applied to GHI data gathered from two distinct locations (Davis and Merced) that represent well the geographical distribution of solar irra...

Locations of contaminant exposure for nesting migratory species are difficult to fully understand because of possible additional sources encountered during migration or on the wintering grounds. A portion of the migratory white-faced ibis (Plegadis chihi) nesting at Carson Lake, Nevada continues to be exposed to dichloro-diphenyldichloro-ethylene (DDE) with no change, which is unusual, observed...

Migratory behavior can be an important factor in determining contaminant exposure in avian populations. Accumulation of organochlorine (OC) pesticides while birds are wintering in tropical regions has been cited often as the reason for high concentrations in migrant populations. To explore this issue, we satellite tracked 16 Ospreys (Pandion haliaetus) over the period 1996-2003 from breeding si...

This paper presents a low VSWR high gain telemetry antenna system manufactured for UAVs that provides 360◦ coverage in the roll plane of the UAV. Proposed telemetry antenna system includes four telemetry antennas, one power divider that has one input and four output terminals which feeds the telemetry antennas with equal magnitude and phase. Proposed high gain telemetry antennas are based on th...

Measurement of physiological parameters in laboratory animals plays an important role in evaluating the biomedical applications. It has been widely known that a telemetry system is useful for these studies, because the telemetry system can obtain physiological measurements from conscious and unrestrained laboratory animals. Maurey was the first to report on a telemetry experiment in the scienti...

During the past 20 years, space communications technologies have shown limited progress in comparison to commercially available solutions on Earth. Such an evolution was not mandatory as Earth-to-Satellite (ESL) communication architecture is still conceived as a telecommand in the uplink, and telemetry and payload data on the downlink. However, communication systems designed to cope with this a...

This is a review of the National Marine Mammal Laboratory's (NMML) Steller sea lion telemetry program. The scope of the review was to focus on four important aspects of the program: The appropriateness of the programming and deployment strategies; the appropriateness of the methods used to retrieve and manage telemetry data obtained from Service Argos; the appropriateness of the stage-based fil...
