KYOCERA AVX has launched an LDS cap antenna and evaluation board optimized for Iridium satellite IoT applications and designated as Iridium Qualified Antenna products for Iridium Certus 9704 modules.
The antenna was developed to provide Iridium with an embedded antenna optimized for low-Earth-orbit (LEO) satellites used to provide seamless connectivity and data exchange for IoT devices anywhere in the world. The new LDS cap antenna developed for Iridium outperforms the ceramic patch antennas traditionally used in these applications.
Manufactured using laser direct structuring (LDS) technology — an efficient process for creating complex, compact, lightweight, wide-bandwidth, and high-gain 3D antenna designs on myriad substrates — the new LDS cap antenna is smaller and lighter than ceramic patch antennas and exhibits excellent right-hand circular polarization (RHCP) and superior gain from zenith to horizon, which maximizes satellite visibility and reliability and is especially beneficial for improving the connectivity of LEO satellites at low elevation angles. It also exhibits wider bandwidth and higher radiation efficiency than patch antennas.
The new KYOCERA AVX LDS cap antenna developed for Iridium supports GNSS (1,559–1,610MHz) and Iridium (1,616–1626.5MHz) frequencies with ~2dBi peak gain and 60% efficiency, and delivers reliable performance in challenging environments, including over metal. It’s rated for 4W power handling, 50Ω feed point impedance, and operating temperatures extending from -40° to +85°C. It’s also proven to withstand exposure to high temperatures, high humidity, and salt spray, compliant with the latest RoHS and REACH directives, and packaged and shipped on tape and reel for automated assembly with reflow soldering.
The on-board antenna has a small, lightweight form factor with a unique design that measures 35.7 mm in diameter and 17.98 mm high, weighs 6.85g, facilitates easy SMT assembly, and allows device manufacturers to locate components on its underside, saving space on the main PCB board.
The new antenna is expressly designed for satellite connectivity, targeted for satellite IoT applications, and well-suited for applications including telematics, asset tracking, remote monitoring, smart farming and smart city applications. Earlier this year, it was shortlisted for Electronic Specifier’s Electronics Excellence Awards in the passive product category.

STMicroelectronics has released an ultra-compact, low-power, narrow-band internet of things (NB-IoT) industrial module with GNSS geo-location capabilities, the ST87M01. The fully programmable, certified LTE Cat NB2 NB-IoT industrial module covers worldwide cellular frequency bands and integrates advanced security features.
The ST87M01 is an integrated native GNSS receiver with multi-constellation access, which ensures enhanced and accurate localization. The module has a diminutive 10.6 mm x 12.8 mm land grid array footprint, making it suitable for applications where a small form factor is key.
The STM8701 offers flexibility for product developers, presenting a fully programmable IoT platform enabling users to embed their own code into the module for simple applications. A variety of protocol stacks are available to handle popular IoT use cases.
The ST87M01 targets wide-ranging IoT applications that require ultra-reliable low-power wide-area network connectivity and has ultra-low power consumption with less than 2 µA in low-power mode and transmit output power up to +23 dBm.
Suitable applications for the module include smart metering, smart grid, smart building, smart city and smart infrastructure applications, as well as industrial condition monitoring and factory automation, smart agriculture and environmental monitoring. The module can also be combined with a separate host microcontroller, permitting many more use cases.
One Galileo satellite has been reconfigured to emit a new signal component optimized to serve low-end receiver devices and internet of things (IoT) applications. According to the European Space Agency (ESA), GSAT0202, in elliptical orbit, was reconfigured in January to transmit the new signal, also known as the G1 E5 Quasi Pilot.
The G1 E5 Quasi Pilot in the E5 band lies along a narrow part of the overall Galileo signal, intended to enable streamlined positioning fixes requiring less calculation — without affecting the E1 and E6 signal bands, on which Galileo also transmits. The initial receiver test showed that the signal component has the potential to reduce the signal acquisition time by a factor of three compared to the current GPS L5 or Galileo E5a signals.

Once GSAT0202 was reconfigured, signal measurements were collected using the high-gain antenna installations from the Galileo in-orbit test facility, which confirmed the stability of the augmented signal. After G1 E5 Quasi Pilot was broadcast, it was successfully acquired and tracked by a set of receivers.
Airbus Defense and Space, Thales Alenia Space Italy, the European Union Agency for the Space Programme (EUSPA), the European Commission, and Spaceopal supported this test.
The other elliptical Galileo satellite, GSAT0201, will also be reconfigured after further testing. Selected chipset manufacturers will be involved in the testing under supervision of EUSPA. The test results will be evaluated at the Galileo Programme level, to eventually introduce G1 E5 Quasi Pilot into the constellation.

With personal or work-issued smartphones, more than 4,000 employees can now use a corporate app to easily find available rooms and spaces to work in the 500,000-square-foot, 20-floor, four-building Stockholm headquarters of telecom company Ericsson.
The Senion StepInside indoor positioning system, designed by partner Flowscape, helps Ericsson employees reduce wasted time searching for people, places or things, thereby increasing productivity.
The StepInside software development kit (SDK) offers location readings in latitude, longitude and floor level in real time. The SDK can easily be integrated into any smartphone application. StepInside relies on an advanced sensor fusion algorithm that works with the smartphone’s movement and radio sensors to provide accurate and robust positioning.
“Indoor positioning technology is perfect for large offices with multiple floors, offices, and meeting spaces — the bigger and more intricate the better,” said Christian Lundquist, CEO and co-founder of Senion. Ericsson’s StepInside implementation is part of the company’s larger global platform designed to enable rapid IoT application development.
The system as implemented today is the starting point for a bigger roll-out with additional workplace enhancements at Ericsson.
Senion’s comprehensive IPS services include analytics, wayfinding, geofencing, friend-finder and tracking. With more than 300 indoor positioning system installations globally, Senion has worked closely with shopping malls, hospitals, corporate campuses and more to improve workflows. Senion is headquartered in Linkoping, Sweden, and San Francisco.
