What Can You Do About Frequency Congestion?

If you are coming up short on usable frequencies in your field studies, there is an answer. At ATS we've developed a coded tracking system that will allow you to track 100’s of terrestrial animals, using the fewest frequency channels. In addition to using fewer frequencies, tracking work can be accomplished more accurately, faster, and with better range than with standard VHF tracking systems.

For many years fish researchers have used coded tagging schemes in their studies, allowing them to track thousands of fish in a compact area, such as a river. Realizing that terrestrial researchers were facing a limitation on the number of frequencies available in the spectrum, ATS engineers set out to develop a system to utilize a coded ID system to track animals on land.

At the heart of the system is ATS' proprietary coding scheme and R4520C Receiver-Datalogger, which enables the researcher to track and identify up to 25 tags sharing a single frequency. While tracking in the field, whether on the ground or in an aircraft, one is able to choose an individual animal within the group, hear only that tag, and locate it with pinpoint accuracy. This receiver features digital signal processing algorithms and so provides excellent sensitivity, allowing target detections faster and at twice the range of other receivers. 

This model is much different then the standard models that make up the R45xx series of receivers. Below is a portion of the receiver's control panel, which shows a view of the keys used to hear or silence certain transmitter ID's. Not shown is the LCD display which will show up to nine of the frequencies within range. 

The other component of the system is the VHF encoded transmitter(s). Each transmitter is assigned a discrete code, (e.g. C-31), but will be assigned the same frequency (e.g. 164.100) on up to 25 other transmitters.

If you'd like a more in depth explanation of coded tracking systems for terrestrial applications, a white paper is available on the ATS website.

ATS Visit to Conservation Biologists Conference a Success


Entrance to the Baltimore venue of the ICCB

ATS attends from twelve to fifteen or more conferences and meetings throughout the world every year. For us, it’s one of the best ways to get in front of and interact with the most important people we work with: our present and future customers.

Our latest conference, the ICCB, International Congress for Conservation Biology, took place in Baltimore in late July. Jon Adsem, ATS Consultant, and Peter Kuechle, ATS’ President, attended this conference, which included almost 1500 registered participants and over twenty exhibiting vendors; one of the largest conferences we attended this year. 

Also present at our booth was our South African representative, Pharm4Game Company. Yolanda Blacquiere and Marna Van Der Walt (Broekman), made the long voyage from Pretoria, South Africa to join us at the conference.

Researchers and students from all over the world visited the conference, and all seemed very excited with the opportunity to mingle and learn from like-minded individuals. The ATS booth was quite busy for the duration of the conference. We spoke with a large number of researchers who were studying animals ranging from elephants to bats, whale sharks to dragon flies, and mountain sheep to snakes!

For this conference we decided to have a little fun by using a more interactive component! All who visited our booth got a chance to enter our “Spin-2-Win” contest using the booth’s iPad. Congratulations to our winners:

Is there a conference you go to that you think could benefit by having a telemetry provider like ATS there? Let us know please!


Newest Telemetry Books (one including a contribution by our own Larry Kuechle)

Two new fish telemetry related books are on our bookshelf here in the Sales and Support department at ATS. And they both have lots of valuable information for those of you getting started in fish telemetry, as well as for seasoned professionals. 

Here they are:

Telemetry Techniques, A User Guide for Fisheries Research. Edited by N. Adams, J. Beeman, and J. Eiler. 

  -- and...

Fisheries Techniques. Edited by A. Zale, D. Parish, and T. Sutton.

In Telemetry Technique's section 5.1, ATS’ own Larry Kuechle and Peter Kuechle (our Engineering Manager and President) authored a section called Radio Telemetry in Fresh Water: the Basics. This paper gives a complete explanation of the primary components of telemetry systems: the transmitter, receiving antenna, the receiver, and appurtenances.

Additional chapters in the book cover design of telemetry studies, transmitter attachment techniques, VHF tracking principles, and case studies. Also presented are chapters covering acoustic telemetry principles and case studies, and overall data management and analysis.

Fisheries Techniques is a broad based book used extensively by fisheries professionals and students. This third edition has been completely rewritten, but the content is similar to previous editions. A chapter is devoted to Biotelmetry and Biologging techniques.

Both are available to order from AFS’ website: http://fisheries.org/shop
