SURVEY & MAPPING Mobile surveying app Increases RTCM 3.1 support SuperSurv’s NTRIP solution is being enhanced to adopt more RTCM versions and provide a better GNSS positioning service. NTRIP (Networked Transport of RTCM via internet protocol) is a protocol to send GNSS-related data through the internet, which enables users of differential GPS or network real-time kinematic (RTK) to get correction parameters after connecting to the internet. The correction parameters can be used to calculate a more accurate GNSS location. Supergeo’s product team is developing the support for RTCM 3.1, including Types 1021 and 1023. Supergeo Technologies, www.supergeotek.com Smart antenna For harsh outdoor applications The scalable A222 GNSS smart antenna is designed for both agriculture and basic indicate systems markets, as well as other markets requiring flexible positioning. The smart antenna has the flexibility to scale and grow as business expands and can be configured from L1-only to multi-GNSS, multi-frequency and real-time kinematic (RTK). It adds a system component so that tractor and farm equipment manufacturers can deliver their own guidance and control solutions to their customers. Designed to excel in challenging environments, the A222 uses Hemisphere’s Athena RTK engine and is Atlas L-band capable. It is easy to mount and customizable. Its dual-serial, CAN and pulse output options are compatible with almost any industry-standard interface. Because the A222 is Atlas-capable, it has the ability to use the new Atlas AutoSeed technology. Atlas AutoSeed allows users to suspend Atlas use for any period, and upon returning to their last location, AutoSeed rapidly re-converges to a high-accuracy converged position. A222 comes pre-configured with Atlas Basic activated. Hemisphere GNSS, hemispheregnss.com OEM Location architecture Locates mobile devices moving indoors and outdoors Leveraging ubiquitous LTE signals, the Lite-Touch Architecture calculates positioning in the cloud to efficiently locate devices between indoor and outdoor environments. By offloading computation-heavy location calculations from the device to the cloud, the PoLTE positioning solution makes location positioning available to a wider variety of devices, including those constrained by battery life, memory, processing power, size and cost. This includes IoT-based applications that historically relied on GPS, with its high rate of power consumption, as well as Wi-Fi and Bluetooth with their added size, cost and network complexity. PoLTE, www.PoLTE.com Time server Enhanced for Ethernet networks, satellite uplinks Enhancements to the SyncServer S600 series of time servers and instruments improve time synchronization over enterprise Ethernet networks and supply timing signals for improved military radar operations and satellite uplink communications. The SyncServer S600 series also meets the timing and synchronization needs of the rapidly evolving networks of enterprise and financial customers, particularly for compliance purposes such as the European MiFID II directive, which specifies highly stringent time accuracy requirements for stock trading systems. The latest release includes support for the IEEE 1588 multiport, multi-profile Precision Time Protocol (PTP), which allows the S600 to operate as an independent grandmaster clock on each Ethernet port — delivering cost savings and network deployment flexibility to customers. This is coupled with a new 10-GbE interface to easily interoperate with a wider variety of network and stock trading topologies.
