Telit Cinterion and Swift Navigation have announced an expanded partnership. Telit Cinterion will offer Swift Navigation’s Skylark Precise Positioning Service as part of an integrated IoT positioning solution.
This service is available with Telit Cinterion’s dual-frequency GNSS modules and NExT cellular connectivity. IoT customers gain one source for the hardware, connectivity and Skylark Dx correction data needed for sub-meter positioning.
What began in 2024 as a technical partnership has grown into a comprehensive joint offering, uniting hardware, connectivity, and corrections into a seamless solution for IoT customers.
Telit Cinterion customers can now buy modules, connectivity and corrections under one contract. For many IoT projects, this cuts vendor coordination and avoids the cost and operational complexity of building or subscribing to an RTK base-station network.
Skylark is available in three variants — Skylark Dx, Cx, and Nx RTK — to meet a broad range of requirements for accuracy, coverage, bandwidth, and power consumption.
All Telit Cinterion dual-frequency L1 + L5 GNSS modules offer native support for Skylark Dx, which streams differential GNSS (DGNSS) corrections directly to the receiver over the cellular network. Skylark Dx runs over standard RTCM via Internet Protocol (NTRIP), using minimal bandwidth and power, and provides country-wide coverage. This makes it practical for IoT devices with limited bandwidth or tight power budgets.
Typical applications include:
e-mobility
fleet and asset tracking
robotics
drones
These are cases that don’t require centimeter-level RTK accuracy but do need reliable sub-meter positioning. Customers requiring higher accuracy can upgrade to Skylark Nx RTK on compatible module variants without redesigning their devices or changing suppliers.
“Customers tell us they want precise positioning without complexity,” said Neset Yalcinkaya, president of IoT hardware at Telit Cinterion. “We’re bundling Skylark Dx with the GNSS modules and cellular connectivity we already ship. This gives customers one supplier and a single integration approach, plus a clear path to RTK down the road.”
“At Swift Navigation, our mission is to make precise positioning a standard capability,” said Holger Ippach, chief operating officer at Swift Navigation. “This partnership advances that vision by embedding Skylark into Telit Cinterion’s GNSS modules and connectivity, giving customers direct access to reliable, sub-meter positioning without the integration overhead traditionally required.”
Service Availability
Skylark Dx is available now with Telit Cinterion solutions in Europe, North America, Japan, South Korea and Taiwan. Coverage will expand as Swift Navigation adds regions.

Quad-band GNSS rover: With support for Galileo high accuracy service
The SparkPNT TX2 quad-band GNSS rover combines an IP67-rated aluminum enclosure with support for Galileo’s High Accuracy Service (HAS) and standard RTK correction workflows. The receiver is built around the Quectel LG290P quad-band GNSS engine and supports multi-constellation tracking. Galileo HAS support provides sub-20 cm accuracy globally without subscription-based correction services, while RTK workflows via NTRIP or u-blox PointPerfect can achieve centimeter-level positioning. Battery life is rated at 50-plus hours, positioning the TX2 for multi-day field campaigns without recharging. The unit connects to iOS and Android devices via Bluetooth and WiFi, with compatibility reported for common GIS and data-collection applications. A notable design choice is the open-source firmware, which gives users visibility into how positioning data is processed and allows for customization and third-party integration. SparkFun has positioned this as an alternative to closed GNSS ecosystems where firmware and processing pipelines are not user-accessible.
Mobile
GNSS platform: Provides ultra-low power GNSS for all environments

Applications include vehicle/ship attitude measurement, UAV attitude reference and trajectory control, mobile mapping, track inspection and underwater highprecision navigation. The U4930 series integrates high-performance MEMS gyroscopes and accelerometers within an independent structure. The three-axis MEMS gyroscopes sense the angular motion of the carrier, and the three-axis MEMS accelerometers sense the linear acceleration of the carrier. The system internally performs compensation for zero bias, scale factor, non-orthogonal error and acceleration-related terms across all temperature parameters, maintaining high measurement accuracy over a long period of time. The module supports custom communication protocols and provides synchronization for GPS/GNSS time data and pulse per second (PPS) signals.
Underground navigation: For navigating mines and unmapped environments
Chimera Land is a 3D laser velocity sensor (LVS) designed to solve the primary challenge for underground mining: maintaining precise vehicle positioning in deep, dark and unmapped environments where GPS cannot reach. When fused with an Advanced Navigation inertial navigation system (INS), Chimera Land allows underground vehicles to maintain stable navigation over extended distances and time. Instead of needing to query an external beacon or satellite for its location, the sensor uses specialized lasers to measure a vehicle’s ground-relative 3D velocity with high accuracy. By feeding this precise data into the vehicle’s INS, the sensor eliminates the drift that typically comes with standalone INS. Using AdNav Intelligence, the result is a resilient, high-performance, infrastructure-light positioning solution that excels in the highdust, zero-light conditions typical of underground mines.
Simulators
GNSS test tool: Provides real-world testing with signals from the field
The SimXTRACT GNSS test tool bridges the gap between field and laboratory. It enables signals captured in field environments to be comprehensively decomposed into individual, discrete signals and applied to lab simulation for realism at every stage of the development test cycle. Developers usually rely on either RF record-and-playback or lab simulation for testing and validation of PNT systems and devices. SimXTRACT takes real signals captured in field environments and performs complex signal decomposition, breaking down each received signal into discrete line-of-sight and multipath ray paths, along with metadata such as Doppler offset, code error, power level and angle of arrival. This decomposed environment is then automatically converted into fully controllable simulation scenarios for Spirent GNSS simulators.
