e- Loran antenna for handheld devices

Register for Final Presentation of the NAVISP EL1-065  Project: "e- Loran antenna for handheld devices"

Enhanced-LORAN (e-LORAN) is the latest in the longstanding and proven series of low-frequency, LOng-RAnge Navigation (LORAN) systems, and provides a PNT service for use by all modes of transport and in other applications. The system operates in the frequency band of 90 to 110 kHz. e-LORAN can improve navigation accuracy and availability through multi‐sensor integration, as well as enhance geo‐security through its jam‐ and spoof‐resistant signal characteristics of high transmit power and low carrier frequency. It can also be used for precision timekeeping. Hence, it is a good candidate as an alternative and/or backup to the (currently non-redundant) GNSS navigation system. 

However, at these low frequencies, classical antennas (generally magnetic loop and loaded monopole antennas) are of large size, which is not adapted to mass-market handheld consumer electronic devices. 

For this kind of market, the antenna has to be miniaturised, by keeping it efficient enough to receive and process e-LORAN signals both outdoors and indoors. 

In order to support the development and the diffusion of the very low frequency application in the PNT service, the development of a new antenna (with dedicated LNA) is considered of crucial importance. The new antenna, developed by Roke shall be mounted on handheld devices for the localisation of users in situations in which the current GNSS is unavailable or degraded.

EL1-065 “e- Loran antenna for handheld devices" was funded by NAVISP Element 1, which is dedicated to technology innovation of the European industry in the wide PNT sector.
