The ILU features 6 RS232/RS422 serial ports, 1 CAN bus, 2 ethernet ports, WiFi and an array of multi-function GPIO pins. All of the interfaces can operate simultaneously with input and output of data in a large selection of different formats. Every single interface is individually optically isolated to prevent grounding issues with other equipment.
The ILU supports data logging from the connected Advanced Navigation device and every other one of its interfaces simultaneously. Data can be automatically timestamped on arrival for easy synchronisation. The system contains 128GB of logging capacity which can allow the unit to log for months.
The ILU functions as an accurate GPS disciplined oscillator and has the capabilities of a full time synchronisation server. Its timing synchronisation outputs include 1PPS, 10 Mhz, hardware PTP as well as a number of other protocol based synchronisation outputs such as NTP and GPZDA.
The ILU features a rich web interface that contains live mapping, real time data plotting and full configuration of devices. The ILU supports all of Advanced Navigation's products and the web interface dynamically reconfigures based upon what it is connected to.
The ILU is housed in a rugged marine grade aluminium enclosure that is water proof and dirt proof to the IP68 standard. The system features surge, static, overvoltage, short circuit and reverse polarity protection on all of its interfaces. Additionally every interface is individually optically isolated to prevent grounding issues with other equipment.
The ILU has support for all of the major protocols including NMEA 0183, NMEA 2000, TSS, PASHR, Simrad as well as a wide variety of proprietary protocols. Support for any other popular protcols will be added on request.
The ILU is ideal for marine survey applications which require multiple serial port data streams going to different equipment. It's ability to simultaneously stream multiple configurable formats and log data at the same time makes it highly desirable for applications such as multibeam sonar. The Ethernet and WiFi interfaces allow for data streaming and monitoring over existing infrastructure as well as wirelessly.
In land surveying applications the ILU allows for easy and reliable data logging as well as logging external timestamped events and synchronising time with other systems. The built in NTRIP client makes RTK with Advanced Navigation's Spatial series of GPS/INS a breeze.
The ILU is an excellent companion for Advanced Navigation's Subsonus USBL where it can break out the Ethernet interface to provide multiple standard serial data interfaces with industry standard protocols. It also allows Subsonus to accept existing ship navigation systems data input.
The ILU is a perfect addition to marine applications that require multiple sources of positioning and heading data. The NMEA 2000 input/output allows for interfacing with a wide range of existing marine equipment.
