GNSS Chip Manufacturers Expect Big Galileo Roll-Out In U.S.

While several smartphone models currently are fitted with chipsets from both Broadcom and Qualcomm Technologies and already have dual-frequency solutions that support Galileo E1/E5a signals, expectations are that we’ll soon see a significant increase in Galileo users coming from the United States.

The Federal Communications Commission (FCC) last fall unanimously approved waivers allowing the use of the Galileo E1 and E5 signals for non-federal purposes in the U.S. Following this waiver, in which it allowed devices in the United States to access signals transmitted by the Galileo Global Navigation System, leading U.S. manufacturers are preparing to roll-out Galileo on U.S. territory.

At a meeting on November 15 of last year, the FCC granted in part a request from the European Commission for a waiver of the FCC rules so that devices in the U.S. may access specific signals transmitted by Galileo.

This decision means that consumers and industry in the U.S. are now able to access certain satellite signals from the Galileo system, which can be used in combination with the U.S. Global Positioning System (GPS). The improved availability, reliability, and resiliency offered by incorporating Galileo capability into devices is something that U.S. chip manufacturers are eager to pass on to their customers, the European Global Navigation Satellite Systems Agency (GSA) said in a statement.

“This is an important market development opportunity for manufacturers in the U.S. The FCC ruling means that industry can now benefit from the use of Galileo signals. The added accuracy and robustness offered by multi-constellation and multi-frequency capability will be a key differentiator on the market,” said Carlo des Dorides, Executive Director of the GSA.

“We are glad to see FCC supporting Broadcom’s dual frequency GNSS vision, for which the GPS and Galileo combination is key,” said Vijay Nagarajan, VP Marketing Wireless Connectivity and Communication Division at Broadcom. “We enabled the world’s first dual frequency GNSS phone in 2018 with the simple goal of providing accurate location to the consumer even amidst the skyscrapers in a busy downtown. We are certain that consumers will benefit from this FCC ruling that will further drive the adoption of dual frequency GNSS.”

“As a leader in developing cellular technology—today, as the world launches 5G and dating back to Qualcomm’s legacy in 4G, 3G, and 2G—including work to incorporate robust navigation solutions for smartphones, Qualcomm Technologies integrated Galileo across its chipset portfolio because we understand the importance and benefits of accurate, reliable, and rapid position location for consumers,” said Dean Brenner, Senior Vice President of Spectrum Strategy and Tech Policy, Qualcomm, in a GSA press release. “We’re excited about the FCC allowing access to Galileo signals in the U.S. for commercial Location Based Services (LBS) because it is a big step forward in improving the user experience, particularly in dense urban environments.”

Activating Galileo in the U.S.
Both Broadcom and Qualcomm Technologies already have dual-frequency solutions that support Galileo E1/E5a signals: the world’s first dual frequency GNSS smartphone, the Xiaomi Mi-8, was fitted with a Broadcom BCM47755 chip and, in December, Qualcomm Technologies launched the newest generation in its 8 Mobile Platform Series—the dual-frequency Qualcomm Snapdragon™ 855 Mobile Platform.

“Approximately 100 smartphone models are already fitted with chipsets from these two manufacturers. Following the FCC ruling, we are expecting to see a significant increase in Galileo users coming from the U.S.,” said Justyna Redelkiewicz Musial, in charge of LBS and IoT market development at the GSA.

Better Positioning, Navigation
The FCC ruling permits access to two Galileo signals – the E1 signal that is transmitted in the 1559-1591 MHz portion of the 1559-1610 MHz Radio-navigation-Satellite Service (RNSS) frequency band, and the E5 signal that is transmitted in the 1164-1219 MHz portion of the 1164-1215 MHz and 1215-1240 MHz RNSS bands.

Access to multi-constellation and multi-frequency capability means that users in the U.S. will be able to benefit from a better positioning and navigation experience particularly in urban environments where the unique shape of the E5/L5 signal makes it easier to distinguish real signals from the ones reflected by buildings, reducing the multipath effect, according to the GSA. The simultaneous use of E5/L5 frequencies also mitigates other sources of error, such as ionospheric distortions, and makes the signal more robust against interference and jamming.
