This paper aims to add the information access capabilities to enable user’s mobile terminals in a wireless small satellite telemetry system. The cellular phone-centric mobile network architecture provides wireless communication link; telemetry information is provided to users in a highly personalized form according to the end-user’s range. We choose a reference system-level model of network arc...

Analysis of satellite-telemetry data mostly occurs long after it has been collected, due to the time and effort needed to collate and interpret such material. Delayed reporting reduces the usefulness of such data for nature conservation where timely information about animal movements is required. To counter this problem, we present a novel approach which combines automated analysis of satellite...

The use of radio telemetry in wader studies has grown exponentially in the past decade, and more than 40 species from four different families have been radio-marked. We summarize these studies and find that nearly all of them have used Very High Frequency radio transmitters to study individuals for periods from a few days to a few months. In the past five years, there has been tremendous growth...

In July 2001, the Space Domain Task Force of the Object Management Group (OMG) issued a Request for Proposal (RFP) on Telemetric and Command Data Specification. This RFP solicited proposals that define telemetry and commanding data specifications in support of all phases of the satellite, payload, and ground segment lifecycle: system design, development, test, validation, and mission operations...

Satellite telemetry devices collect valuable information concerning the sites visited by animals, including the location of central places like dens, nests, rookeries, or haul-outs. Existing methods for estimating the location of central places from telemetry data require user-specified thresholds and ignore common nuances like measurement error. We present a fully model-based approach for loca...

We present a method for on-orbit, attitudeindependent magnetometer calibration that includes the effect of time-varying bias due to electronics on-board a spacecraft. The calibration estimates magnetometer scale factors, mis-alignments, and constant as well as time-varying bias. Timevarying effects are mitigated by including spacecraft telemetry in the measurement model and estimating constant ...

This paper presents a method to summarize massive spacecraft telemetry data by extracting significant event and change patterns in the lowlevel time-series data. This method first transforms the numerical timeseries into a symbol sequence by a clustering technique using DTW distance measure, then detects event patterns and change points in the sequence. We demonstrate that our method can succes...

1. Biological and statistical complexity are features common to most ecological data that hinder our ability to extract meaningful patterns using conventional tools. Recent work on implementing modern statistical methods for analysis of such ecological data has focused primarily on population dynamics but other types of data, such as animal movement pathways obtained from satellite telemetry, c...

Four adult (2M:2F) snow leopards (Uncia uncia) were radio-monitored (VHF; one also via satellite) year-round during 1994– 1997 in the Altai Mountains of southwestern Mongolia where prey densities (i.e., ibex, Capra siberica) were relatively low ( 0.9/km). Marked animals were more active at night (51%) than during the day (35%). Within the study area, marked leopards showed strong affinity for s...
