GNSS solutions for enhanced railroad operations

All of these measures are essential for PTL. However, the roof of a locomotive is a less than ideal environment with various metal surfaces, large ground planes, and other antennas operating in proximity. Calian has the experience and tools to ensure that train operators avoid potential problems and select the ideal antenna for the situation and optimal placement.

Extending the ability of PTL to Hi-Rail vehicles can also improve productivity and safety. Many of the issues with respect to placing antennas on locomotives apply to placing precision antennas on Hi-Rail vehicles.

Additionally, determination of the end of train to within centimetres can improve safety and productivity. Placing a GNSS antenna on an end-of-train device to provide the required level of accuracy is fraught with many compromises and issues. Calian has the experience and expertise to assist in making the inevitable compromises.

With the availability of more Global Navigation Satellite Systems (GNSS) constellations, the proliferation of GNSS signals (including L2 and L5), and the decreasing costs of precision, there is significant opportunity for railroad operators to increase the safety and reliability of their systems.

Railroad operations subject GNSS systems to the most varied operating environments. Through the transit of a single train, the GNSS system is exposed to changing weather conditions, vibration and shock, as well as reduced sky view. GNSS antennas must have the robustness to reliably operate in all environments.

There is a growing number of geographic areas where inter-modulated cellular and other radio signals (such as the 700MHz band) have the potential to cause interference for GNSS systems. In response to this, Calian offers a range of robust GNSS antennas with pre-filters designed to mitigate the effects of such signals. Robust pre-filtered antennas are available in single, dual, and triple band GNSS versions for all GNSS constellations. Additionally, these antennas are available in a variety of compact sizes and economical prices.

Key features include:

  • (TW3972) AAR certification (S-9401.V1.0)
  • (TW3972) European Railway certification (EN45545-2, EN50121, EN50155, and EN61373)
  • Accurate and precise positioning with Calian’s patented antenna technology
  • Excellent multi-path rejection for superior performance in high multi-path/reflection environments
  • Multi constellation coverage to maximize the number of observations available for position and time estimation (GPS, QZSS, GLONASS, Galileo, BeiDou, and NavIC)
  • Multi-signal and multi-band support
  • Optional pre-filters to enhance out-of-band signal rejection
  • Embedded versions for use in custom enclosures with custom-tuning available
  • Wide voltage range for broad receiver compatibility
  • Strong electrostatic discharge immunity
  • Magnetic, thru-hole mount, or 5/8″ x 11 TPI mount antennas
  • NMO antenna mount option
  • Robust enclosures
