The GSA White Paper on Power-efficient positioning for the Internet of Things provides an overview of GNSS technologies that are relevant for low-power IoT applications, including those that require hybridisation with other connectivity solutions. Participants in the webinar were introduced to the main findings from the paper.
Also presenting were GEONAV IoT, which is working to develop and deliver precise ubiquitous positioning and navigation applications and services; and Galileo of Things (GoT), which is targeting the delivery of a Galileo semiconductor-IP core that mates with NB-IoT IP for low-power consumption solutions.
In light of the power-saving solutions highlighted in the GSA White Paper and discussed during the recent webinar, it is clear that GNSS industry is listening to the needs of the IoT community so that the most accurate positioning solution can play an increasingly important role without depleting the precious batteries of the devices.

Intelligent positioning solutions provider Aptella announces the release of MiRTK. This new correction service for GNSS equipment utilises the internet instead of UHF radio frequencies. MiRTK is compatible with all brands and models of GNSS from manufacturers including Topcon, Trimble, Leica Geosystems, Sokkia, Hemisphere and more.
ORGN partners and subscribers with valid ORGN rover accounts have access to real-time kinematic correctors computed by Leica Spider software. These correctors are served over the internet and accessed by the user via a cell modem connected to a GNSS rover in the field.
Bancroft's method is algebraic, as opposed to numerical, and can be used for four or more satellites. When four satellites are used, the key steps are inversion of a 4x4 matrix and solution of a single-variable quadratic equation. Bancroft's method provides one or two solutions for the unknown quantities. When there are two (usually the case), only one is a near-Earth sensible solution.[170]
Leick et al. (2015) states that "Bancroft's (1985) solution is a very early, if not the first, closed-form solution."[183]Other closed-form solutions were published afterwards,[184][185] although their adoption in practice is unclear.

The Geode can use network corrections from this internet-based service. Getting this data from these real-time networks requires using the Geode Connect software or another application and an internet connection to connect to a network and decode the messages for the receiver.
Some limitations include the network being managed and configured in diverse ways, requiring a device that can connect to the internet, and generally covering smaller regions. In addition to these limitations, users should consider that this service may or may not have subscription costs that vary.
To level the playing field and ensure all operators can be part of the 5G revolution, they need to leverage technology solutions that can help them upgrade their network infrastructure to meet synchronization requirements quickly, securely and cost effectively.
5G mobile networks also bring increased demands on cell density, indoor cell coverage and deployment in challenging geographical areas, including tunnels, buildings and factories where satellite visibility is challenging. Likewise, geography and landscape impacts GPS-dependent solutions that find it hard to deliver in areas with limited satellite visibility, such as urban areas where buildings obstruct the view and rural areas with deep forests and canyons.
While the aforementioned are the main 5G synchronization models, there are further synchronization technologies that could be considered for 5G mobile networks. For example, White Rabbit combines PTP and SyncE and introduces additional mechanisms to improve synchronization accuracy. White Rabbit is specifically designed to meet the stringent requirements for particle accelerators and is typically used in dedicated fiber or LAN environments. However, White Rabbit requires dark fibers between dedicated timing nodes, which makes such solutions too costly for national rollouts. A further alternative approach is Over-the-Air Time synchronization (OTA), which is designed for ultra-reliable and low-latency communications (URLLC). OTA is a radio interface-based synchronization solution that has been used for synchronizing base stations in 4G/LTE and is an alternative that is put forward for 5G mobile networks in the RAN (Radio access Network) but does not scale for the backhaul and WAN network.
Time synchronization is critical for 5G to function, and Türk Telekom early realized the cost and complexity of enabling existing PTP (Precision Time Protocol) solutions across their large national network. Türk Telekom experienced that dependence on GPS/GNSS can cause 5G services to be affected and therefore proactively decided that their 5G network must be independent of GPS or other GNSS solutions.
As part of the 5G/DSS rollout process Türk Telekom executed an extensive inspection of the existing network and identified a critical challenge. The recommended PTP synchronization standard for telecom profiles requires hardware and/or software upgrades to meet the high demands for 5G, and vendors solutions might not always be compatible with each other. In addition, the cost and complexity of rolling out and operating a large-scale nationwide PTP network is significant.

Nowadays, the availability of affordable multi-constellation multi-frequency receivers has broadened access to accurate positioning. The abundance of satellite signals coupled with the implementation of ground- and satellite-based correction services has unlocked the potential for achieving real-time centimetre-level positioning with low-cost instrumentation. Most of the current and future applications cannot exploit well-consolidated satellite positioning techniques such as Network Real Time Kinematic (RTK) and Precise Point Positioning (PPP); the former is inapplicable for large user bases due to the necessity of a two-way communication link between the user and the NRTK service provider, while the latter necessitates long convergence times that are not in keeping with kinematic application. In this context, the hybrid PPP-RTK technique has emerged as a potential solution to meet the demand for real-time, low-cost, accurate, and precise positioning. This paper presents an Internet of Things (IoT) GNSS device developed with low-cost hardware; it leverages a commercial PPP-RTK correction service which delivers corrections via IP. The main target is to obtain both horizontal and vertical decimetre-level accuracies in urban kinematic tests, along with other requisites such as solution availability and the provision of connection ports for interfacing an IoT network. A vehicle-borne kinematic test has been conducted to evaluate the device performance. The results show that (i) the IoT device can deliver horizontal and vertical positioning solutions at decimetre-level accuracy with the targeted solution availability, and (ii) the provided IoT ports are feasible for gathering the position solutions over an internet connection.

The primary mechanism for managing the data from these stations, and for creating the real-time outputs, is commercial RTN software, although investment has been made in substantial customization, for instance in account and invoicing management, and its own online post-processing service. SWEPOS began with GPSNET, from the German GNSS developer Terrasat (now part of Trimble) two decades ago and continues to this day. The software continued to evolve, and is presently Trimble Pivot Platform, one of the most widely implemented RTN suites globally. SWEPOS uses Pivot to help determine station velocity and has a module to apply this to the solutions. In addition to the CORS, monitoring stations are also included in the network to check the quality of GNSS solutions.
Adtran today launched new synchronization solutions featuring Satellite Time and Location (STL) technology to address the growing vulnerabilities of GPS and other GNSS systems to jamming and spoofing attacks. Alongside GNSS-based timing, the OSA 5405-S PTP grandmaster clock can now receive STL signals. This compact and versatile device caters to a diverse range of indoor and outdoor deployment settings, serving industries from 5G and data centers to smart grids and defense. Also available from the Adtran Oscilloquartz suite is the OSA 5400 STL module, which brings the benefits of a compact STL/GNSS receiver to third-party switches and servers. STL harnesses low-earth orbit (LEO) satellites as a distinct time source, offering not just an effective alternative to GNSS but also enhancing it with greater reliability and security. This dual-source approach aligns with zero-trust principles, ensuring resilience even in the event of GNSS disruption.
