There are generally four categories of transmitter in the CTT Internet of Wildlife (IoW)™: GPS+GSM, GPS+Radio, Satellite, and Digital ID Radio. Each has certain requirements in order to make a complete system, and there are some universal options and services we offer. You can read about our payment terms here too.
This category of transmitter, invented by CTT in 2005, will help you track larger animals (generally 600g or more). CTT is now in our 4th generation of GPS+GSM wildlife trackers. Generally offered as solar recharging, the most important selection to make is the total weight your research animals will bear and the attachment style. The second most important set of decisions comprise the transmitter’s duty cycle. This is the frequency of time-dependent GPS fixes you want to record in a given time period, the number of times per week you want the transmitter to upload its data, and if options like the CTT Activity Index™ or Flight Mode™, and geo-fences, will be required, what conditions trigger them and what happens when they fire. Optional items for some GPS+GSM transmitters are Smart VHF™ and Argos data transmission. With CTT GPS+GSM transmitters, these are very helpful in recovering your transmitter from limited access locations in the event a tagged animal dies.
CTT provides a simple, flat-rate annual GSM, data access and analytical platform that includes GSM service in all but three countries. With CTT, you need not contact any carrier for service or a SIM card. We do that for you.
Argos requires you have an account and device identification from them for the transmitters you may want to use on their constellation. CTT will add the Argos information to the devices we build for you that have Argos enabled, but we will need you to provide the Argos device IDs.
CTT’s radio transmitters rely on CTT base stations to deliver your telemetry data. These GPS units are made to be lighter because the GSM, Argos, or WiFi network functions are performed by the base stations. Generally offered as solar recharging, CTT radio transmitters can be battery-only. Like the GPS+GSM transmitters, the most important selection to make is the total weight your research animals will bear and the attachment style. The second most important decisions define the transmitter’s duty cycle. This is comprised of the number of time-dependent GPS fixes you want to record in a given period, and the number of times per week you want the base station(s) to upload data. Optional items for CTT radio transmitters are Smart VHF™ and Argos data transmission network. Smart VHF is designed to help you recover your transmitter in the event your animal dies. Argos is an excellent and well known wildlife research satellite constellation.
CTT is a partner with Argos, the dominant satellite constellation for wildlife research. Our Argos tags can provide location information using the Argos satellites or GPS, and transmit the data over the Argos constellation. Highly efficient solar recharging or battery-only transmitters are available and extremely reliable. Like with the other transmitter technologies, the weight your animal will bear, their behavior, and scientific questions you want to answer will drive decisions about the housing, tag weight, attachment and duty cycle.
Digital ID Radio
CTT’s Digital ID Radio can be deployed with as few as three items, or over a dozen if you are putting up new base stations. CTT Life Tags are right for animals requiring a sub-gram to maximum two gram transmitter weight limit, and get sufficient exposure to sunlight. CTT Power Tags are the battery powered version of the Life Tag and are excellent transmitters for bats and nocturnal small mammals. Besides which type of tag, attachment is the other important choice to talk over with your CTT partners.
Standard CTT IoW base stations can be comprised of strictly CTT components or you can choose to leverage the extensive infrastructure of our partners at Bird Studies Canada who operate the Motus network. If the former, you will want to get the basic CTT Base Station, and select the appropriate antennas, mounting system(s), power configuration, and data transmission. Power options can be A/C or solar, and 12v DC or 10,000MAH LiPo battery. Data can be retrieved from the station by copying the files from an SD card, or selecting a transmission network including GSM, WiFi, Motus or the Argos satellite constellation.
CTT Nodes and Nest Box receivers provide very localized tag detections and automatically upload detection data to standard CTT base stations. CTT Nodes, set up in a grid, provide detection location data at a finer level, allowing you to plot the movement of the smallest animals in your study area. The CTT Locator and app allows you to confirm the CTT digital tags are transmitting properly before you release your animal, but also locate the tag and animal in the field after.
Transmitter formats can be mammal ear tags, flipper attachments, implants, avian backpacks, leg mounts for cranes, waterfowl collars, and in the case of CTT Life Tag, embedded into standard livestock tags.
Choices for attachment techniques include harness, leg loop, ear tag, implantation and adhesive.
Sometimes, you actually are the first to try something. We applaud you for making it this far! Being the first may mean you need some technological development in order to get the data you need. We’re ready. Take a look at the program we offer to help you define your vision and make it a reality.
Field Services, including trapping and tagging of certain species, are performed by our consulting partners.
It all comes down to Data Analysis, and crunch time is no time to find out you could use some additional depth. Our partners at Conservation Science Global are expert with data modeling. Contact them and talk about what you need.
Keep your fleet of CTT transmitters and base stations in top form with our Refurbishment and Replacement program. For a low flat fee at the time of purchase, you can return certain items to us for extended storage, a one-time refurbishment, or replacement.
Downpayment is required for new customers who are ordering on behalf of a NGO. We accept payment via check, wire transfer and PayPal. Typically, payment terms are net 30, and we invoice upon shipment, or in advance for downpayment. We’re also researchers and want to support your work, so talk to us. There may be another way that works for both of us. Some items are available for rent. We provide assurance on your CTT GPS+GSM transmitter for one year. Account set up, shipping and handling is an additional charge. In addition to having your CTT order delivered, this one-time fee covers the cost of setting up your transmitters on our management and data platform.
