Questions related to Telemetry Systems
I am currently working on the development of VHF telemetry system for wildlife. I want to know about whether there are any frequency related or any other regulations for tracking the wildlife in India or I can simply design transmitter and receiver at ISM frequencies.
Hello guys
Do you have any recommendations for telemetry systems ? focusing in EEG recordings?
Thanks a lot in advance
I have a broad range of questions about those systems.
I need to buy a telemetry system and I need help. I want DSI but I have better price offers. My problem is that I do not know if the data provided by other producers are real or not.
The idea is to use a "normal" GLS in combination with a pre-programmed, possibly weight-reduced GPS logger that switches on/off at defined dates (let's say 4 weeks before/after the equinoxes) and also under constant light (or dark) conditions; the latter is basically in function like a saltwater switch, but working with information on light. When active, the GPS would log 2 positions a day (no finer resolution needed than with the GLS working for the rest of the year), therefore saving battery life and reducing size. No trouble in using a GPS logger, since the bird has to be recaptured to get at the GLS anyway.
This would be an alternative to a) having to skip several weeks to months of logged data for analysis because latitude could not be determined reliably with GLS and b) calculations/modelling environmental variables recorded during equinoxes/midnight sun to get an idea of likely geographical locations at the time.
The idea crossed my mind in Sept 2015 and I asked around a bit in Dec 2015 at uni, etc. Neither then nor now, have I found literature on anybody having tried/working on this. There is some literature on "combined-" or "double-tagging", but with the purpose of estimating the GLS' s accuracy, not to get data during the equinoxes.
Has anybody tried this?
What would be obvious pitfalls? (I know, weight of the GPS logger is an issue for smaller species.)
How small can a GPS logger be, when it's necessary to log only about 500 locations? (4 weeks before/after each equinox = 112 d = 224 loggings PLUS midnight sun on Svalbard max. ~ 126 d = 252 loggings. That gives a total of 476 loggings.)
How difficult is the programming?
- Getting it to switch on and off at a defined calendar date cannot be too complicated. How about programming it to switch on when there's 24 hrs constant-light conditions?
Which companies/working groups are specialized on non-standard things like that?

I wanted to get some assistance regarding the above topic. I am to design and implement a water leak detector system for home use as part of a water usage management system. The system must
1. Detect a leak
2. Interface with a control system so that the smart meter can be automatically shut down remotely
Please advice on the projects relation to the use of telemetry for implementation and how one should/would go about it.
Thank you
Distribution RTUs are deployments of large numbers
of units over a broad geographical area. Small number of data
points and complex communication structures are common in
these applications.
I am looking for any devices (especially telemetric) that are capable of monitoring real time the human performance (e.g. during running, or roller skating). Any device counts which suitablly monitors pulse, speed, blood lactate, blood pressure etc. For example Team Polar or Polar RC3GPS. Preferably the devices with the more types of data would be better.
Does anyone have experience with any drop off tools on small animals (e.g. hare, marten, or even smaller)? We want to collar hares with e-obs-GPS-collars but need an additional drop off mechanism so that they lose the collar after a certain period of time, and we can get it back. Any suggestions?
