The GPS Flight Recorder for Homing Pigeons Works: Design and First Results
2015Co-Authors: K Von Hunerbein, H J Hamann, Wolfgang Wiltschko, E RuterAbstract:This paper describes a first version of the GPS flight recorder for homing pigeons. The GPS recorder consists of a hybrid GPS board, a patch antenna 19*19 mm, a 3 V Lithium battery as power supply, a DC-DC converter, a Logging Facility and an additional microprocessor. It has a weight of 33g. Prototypes were tested and worked reliably with a sampling rate of 1/sec and with an operation time of about 3 h. In first tests on homing pigeons 9 flight paths were recorded, showing details like loops flown immediately after the release, complete routes over 30 km including detours, rest periods and speed. For several years we have tried to develop a GPS flight recorder, specifically designed for homing pigeons in order to accurately measure flying positions and record their flight paths [2]

Flight tracks of homing pigeons measured with GPS
2006Co-Authors: Hünerbein, Karen Von, Rüter Eckhard, Wolfgang WiltschkoAbstract:Flight paths of homing pigeons were measured with a newly developed recorder based on GPS. The device consists of a GPS receiver board, a Logging Facility, an antenna, a power supply, a DCDC converter and a casing. It has a weight of 33g and works reliably with a sampling rate of 1/s with an operation time of about 3 h, providing timeindexed data on geographic positions, ground speed and altitude. The data are downloaded when the bird is recaptured. The devices are fixed to the birds with a harness. The measured complete flight paths show many details: e.g. initial loops flown immediately after release and large detours flown by some pigeons. We are here presenting 3 examples of flight paths from a release site 17.3 km Northeast of the home loft in Frankfurt. Mean speed in flight, duration of breaks and length of the flight path were calculated. The pigeons chose different routes and have different individual tendencies to fly loops over the village close to the release site

a gps based system for recording the flight paths of birds
Naturwissenschaften, 2000Co-Authors: K Von Hunerbein, H J Hamann, E Ruter, Wolfgang WiltschkoAbstract:The GPS recorder consists of a GPS receiver board, a Logging Facility, an antenna, a power supply, a DC-DC converter and a casing. Currently, it has a weight of 33 g. The recorder works reliably with a sampling rate of 1/s and with an operation time of about 3 h, providing time-indexed data on geographic positions and ground speed. The data are downloaded when the animal is recaptured. Prototypes were tested on homing pigeons. The records of complete flight paths with surprising details illustrate the potential of this new method that can be used on a variety of medium-sized and large vertebrates.

remote Logging in java using jeli a Facility to enhance development of accessible educational software
Technical Symposium on Computer Science Education, 2000Co-Authors: Steven RobbinsAbstract:The combination of Java and the World Wide Web has opened up new opportunities for teaching at all levels. It is now possible to assume that all students in a class have access to the web through a browser that supports the Java language and a standard subset of the GUI API. One of the drawbacks of using Java through a browser is the lack of a standardized safe way for a Java applet to access resources on the local machine. Security measures prevent the applet from storing information generated by the applet on the local machine. The Jeli package contains a Logging Facility that allows an applet to store files either locally (if permitted) or on the server from which the applet was loaded. Jeli Logging makes it significantly easier for instructors to develop applets that can permanently store information generated by user interaction with the application. The log can then be used by the student for study or the instructor for grading.
