- The system can be programmed to store high accuracy standard GPS and/or QFP-GPS positions in memory. QFP-GPS is Telonics' new rapid fix GPS technology that obtains the data necessary to calculate a GPS positions in as little as 3-5 seconds. QFP-GPS technology has been used in marine applications for several years and is now making its way into terrestrial applications. The technology can be used to increase the number of positions collected or extend the time over which positions are collected by as much as 3-6 times relative to standard GPS positioning. Location accuracy for GPS/QFP-GPS is virtually the same as standard GPS.
- Other biologically significant data that can be collected include activity level, temperature, and mortality events. For some marine mammal applications (e.g., polar bears) a saltwater switch can provide information on time spent in and out of sea water.
- Real-time clock calendar (RTC) controls all timing functions and is re-synchronized with GPS time to assure high accuracy event timing.
- All products can be programmed by Telonics Product Programmer (TPP) which uses a graphical user interface. TPP makes it possible for users to program their own systems and simulate performance of the system prior to deployment.
- On-board sensors can be activated or deactivated in the field. Data collection regimes and schedules can be altered as required. Collected sensor data can be selectively included in Iridium uplink transmissions.
- Data Decoding - Data are processed using the Telonics Data Converter (TDC), which supports both the Iridium data collection distribution and the direct download of memory using the TSC-4 or the TSC-7 cable. TDC provides a comma separated value (csv) output file with time stamps for all data collected, along with a map location for use in Google Earth. TDC can be run interactively, or in "batch mode" for hands-off operation. TDC allows you to plot GPS fixes and QFP-GPS locations for presentation using Google Earth.
- Shutdown with a small magnet allows users to turn each of these configurations "on" or "off". When turned "off", TGAV-4xxx series based units consume less than 12 µA. Given these low current levels, users can store their units for extended periods with minimal impact on operational life.
- Units can be refurbished to their original condition at the factory.
Iridium Data Transfer System Features - Show
- Complete global coverage with 66 satellites in the constellation orbiting at 780 km above the earth. Upgrades to these satellites will take place starting in late 2015, continuing through 2017.
- Intra-satellite communication means that signals do not rely on ground stations being in-view to transfer data and the system has true worldwide coverage.
- Two-way communications allows for confirmation of received transmissions, so the system does not need to resend data over and over again.
- The system is always available for real time data transfer.
- Models with support for geofencing and auxillary schedules are available.
Controlling Data Acquisition and Transmission Using Geofencing
A geofence can be described as a virtual boundary around a physical geographical space, defined by a set of coordinates surrounding an area. Geofences may be established and maintained by a range of GPS-enabled devices including smartphones and devices designed for commercial applications like trucking and farming. Geofencing has also proven to be a useful tool for many animal tracking studies.
Although different animal telemetry manufacturers implement geofencing features in different ways, there are basic similarities in that geofencing is a mechanism that allows one or more geographical areas to be defined and provides customized data acquisition and transmission behavior based on whether the study subject is in "inside" or "outside" the geofence(s). A study subject is considered "inside" when inside any defined geofence, and is considered "outside" when outside all defined geofences.
Note that the speed of detecting that an animal has crossed a boundary and is now in or out of a geofenced area will depend on how much time has elapsed between crossing the boundary and acquisition of the next GPS position. Therefore the rate at which fix attempts are scheduled directly influences the time it will take the unit to detect boundary transitions. Also note that since QFP-GPS data do not provide a resolved position until post processing has occurred, acquisition of QFP-GPS data cannot contribute to the detection of boundary transitions.
- Telonics GPS/Iridium systems can support many geofenced areas, which may overlap. Multiple geofence types are available to establish area(s) of special interest:
- Rectangle - upper left and lower right coordinates are specified.
- Circle - center point and radius are specified.
- Polygon - Up to 50 points may be specified. Polygons may be concave or convex, and may be "closed" (last point and first point are the same), or "open" (first point and last point are not the same).
- Separate Inside and Outside schedule sets are provided to control:
- Acquisition for QFP-GPS, GPS, underwater, activity, and temperature data
- VHF Beacon transmissions
- Iridium transmission behavior specified by date range: transmission interval, transmission retry delay, and message expiration
Controlling Data Acquisition and Transmission Using Auxiliary Schedule Sets
Iridium SBD (Short Burst Data service) is a two-way messaging system. Information can be recovered from and also sent to an Iridium system deployed in the field. The simplest use of the two-way capability is the acknowledgement of message data received from a system in the field to assure that the deployed system can stop sending old data and proceed to send newer data. In more sophisticated Iridium systems, other messages can be sent to the deployed unit. Telonics GPS/Iridium systems take advantage of the two-way communications to alter the behavior of the system in the field, as specified by the researcher.
Auxiliary schedules are created in TPP. TPP can then send email to Iridium to instruct the deployed unit to switch schedules. The unit will then switch schedule sets the next time it connects to the Iridium network, which typically happens on a daily basis. In addition to the default schedule set, which controls all data acquisition and transmit behaviors. Auxiliary schedule sets are useful for increasing or decreasing the intensity of data collection and/or data transmission. Auxiliary schedule sets are also useful for adjusting the VHF beacon duty cycle to save energy when there are no plans to be out in the field monitoring units with a VHF receiver.
- Auxiliary schedules provide the capability to control:
- Acquisition of QFP-GPS, GPS, underwater, activity, and temperature data
- VHF Beacon transmissions
- Iridium transmission behavior specified by date range: transmission interval, transmission retry delay, and message expiration
- GPS/Iridium systems can be directed to execute an Auxiliary schedule (or return to the default schedule) by sending commands over the Iridium data link.
- Commands to GPS/Iridium systems are sent via email using TPP. Internet connectivity and an email provider are required.
- After receiving a schedule change command, GPS/Iridium systems will switch to the specified schedule immediately and will continue to execute that schedule until directed to do otherwise.
