APS3G’s are marching out the door

Satisfying the RTK GNSS needs of provinces and water districts is demanding.

Today we prepare 2 x Septentrio APS3G’s using the Juniper Allegro 2 field tough computers to connect with an existing AsteRxU base receiver to provide RTK correction via the Internet.

Just over a year ago the water district engaged Elliott Enterprises to develop a solution for a city wide RTK GNSS system to provide accurate height data to design a 21st century water system to deliver water to the household at the right pressure on demand. After some testing and R&D we recommended an Altus Positioning System.

Upper Cases: 2 x APS3G Kits for Internet connection via GSM. Lower Case: APS3G RTK kit

Upper Cases: 2 x APS3G Kits for Internet connection via GSM.                        Lower Case: 1 x APS3G RTK kit Peer-to Peer UHF radio

The third case (on the floor) consists of 2 x Septentrio APS3G’s as an RTK GNSS Kit with a Juniper Allegro 2 field tough computer to operate Carlson SurvCE software for road design, drainage design and subdivision developments across a province.

The Altus Positioning System is chosen consistently for speed, accuracy and versatility in the most challenging surveys. With free firmware for the life of the receiver, the province will enjoy continued free upgrades and support for an even better survey solution for many years to come.

Septentrio seismic monitoring and advanced CORS

Leuven, Belgium and Torrance, California – 8 December – Septentrio, a leading provider of accurate and reliable GNSS receivers, announces today the release of 5.1.0 firmware for the PolaRx5 product line of GNSS reference receivers. The 5.1.0 firmware brings new features for file management, usability, security and seismic monitoring. Septentrio’s PolaRx5 product line of GNSS reference receivers includes the PolaRx5 for CORS and network operations, the PolaRx5TR for time and frequency transfer and the PolaRx5S for space weather applications.

Improvements in Precise Point Positioning (PPP) has opened the door on seismic monitoring using GNSS technology.  As well as allowing precise measurement of long-term slow surface displacement, PolaRx5 now allows real-time recording of the high-frequency vibrations typically accompanying earthquakes. Firmware 5.1.0 introduces the support for on-board PPP and dynamic response tuned for seismic applications.

The 5.1.0 firmware release brings greater logging efficiency to the PolaRx5 users. Storage integrity is crucial for many applications. Re-transmitting data can be an expensive business, especially when using Iridium telemetry.  To improve archival functionality, Septentrio has developed a storage integrity feature to retransmit only the data which has been lost in the initial transmission. This avoids the common and unnecessary overhead of re-transmitting complete files.

Preventing unauthorised access is a crucial aspect of cyber security. PolaRx5 product line is now equipped with firewall and IP filtering, SFTP and ssh keys. This complements and strengthens the user management and access level protection of the PolaRx5 product line.

Various independent tests have shown PolaRx5 consistently ranks highest among GNSS receivers in many areas of measurement quality, including lowest measurement noise and fewest number of cycle slips, and this at the lowest power consumption on the market. The PolaRx5 products offer robust and high-quality GNSS tracking of GPS, GLONASS, Galileo and BeiDou as well as regional satellite systems including QZSS and IRNSS.

Some of those who have recently deployed the PolaRx5 include the Oregon Department of Transport (DOT), UNAVCO, the Jet Propulsion Laboratory (JPL) and the SAPOS CORS network in Germany.

“The 5.1.0 PolaRx5 firmware continues Septentrio’s commitment to its customers.” stated Francesca Clemente, PolaRx Product Manager. She continued: “The new features of the 5.1.0 firmware complement existing standard features of the PolaRx5 GNSS receivers such as Advanced Interference Mitigation technology (AIM+) and the web UI offering full user control and status to make PolaRx5 the most complete GNSS reference station on the market today.”

This firmware is now available on Septentrio’s website and will be showcased at the American Geophysical Union (AGU) Fall Meeting from Monday, 12 December.

Septentrio receiver tracks newest Japanese GNSS signals

Hong Kong – 12 October 2016Septentrio and its Japanese partner, GNSS Technologies, are proud to announce that they have successfully tracked and decoded the QZSS LEX signal. This achievement marks a milestone in the development of the Japanese QZSS satellite navigation system and is the result of a trusted partnership between Septentrio and GNSS Technologies. The partnership is committed to enable the success of their Japanese customers with the very latest in satellite navigation technology.

QZSS (Quasi-Zenith Satellite System) is Japan’s regional satellite navigation system. When completed, it will consist of 4 satellites: the first satellite was launched in 2010 and the remaining three are scheduled to become operational in 2017. All satellites will be equipped with a revolutionary CLAS (centimetre-level augmentation service). This service will send correction signals straight from the QZSS satellites to end-user receivers and enable them to calculate their position with centimetre-level accuracy. The CLAS corrections are broadcast in the LEX and L6 signals.

By implementing LEX signal tracking and decoding before the completion of the QZSS constellation and before the CLAS service becomes operational, Septentrio and GNSS Technologies are showing their long-term commitment to Japanese customers.

Using Septentrio technology, customers will be able to eliminate the need for investment in ground infrastructure to create correction signals or in subscriptions to commercially available correction signal streams. This opens up possibilities in new application domains in sectors such as marine, construction, agriculture, survey and mapping, geographic information systems (GIS) and unmanned aerial and vehicles (UAVs).

How GPS brings time to the world

 Knowing the correct time is something we take for granted but who is it that decides what the correct time is? How do they determine it? And where does GPS fit in to the story?

Banner Theme 3 GEOtime

The short answer: the International Bureau of Weights and Measures (BIPM, Paris), as well as telling us the length of 1 metre also tell us what time it is. To determine the time, they rely on the contributions from a worldwide collaboration of timing laboratories who each maintain their own measure of time and compare it with GPS time.


One clock to rule them all

Timing labs employ precise clocks, with Cesium atomic clocks and Hydrogen masers being among the most popular. Although these clocks are very reliable (accurate to about 2 nanoseconds per day) there are still small variations. At BIPM in Paris, they compare the performance of clocks in timing labs around the world and, by using a weighted average of all contributions, calculate what is known as UTC (Coordinated Universal Time). Labs with better performing or more stable clocks are given more weight in the calculation of UTC.


Figure 1: UTC time is the result of input from many timing labs around the world


This means that real-time UTC is only an approximation albeit a very accurate one, with the more precise calculation determined retrospectively. The Circular-T journal, published monthly by BIPM contains the small corrections to be applied to UTC during the previous month.

Where do GPS receivers fit in?

Each timing lab contributing to UTC measures its own version of UTC for example, UTCBrussels is the Belgian measure of UTC. So how does BIPM compare the performance of all these different clocks? The answer is that it uses the GPS receivers or more accurately, GNSS (Global Navigation Satellite System) receivers which besides GPS, also track constellations such as GLONASS, Galileo, BeiDou and IRNSS.

The precise measurement of time is at the heart of every GPS receiver. The distances between satellite and receiver, used to calculate position, are determined by measuring the transit times of the satellite signals to the receiver. An error of 1 nanosecond in the transit time translates into an error of 30cm in the distance. The GPS satellite constellation uses its own precise measure of time called GPS time with each satellite having its own, on-board set of atomic clocks. Satellites can thus be viewed as very accurate flying clocks.

By tracking a GPS satellite, a receiver can record the time differences between its own receiver clock and the satellite clock, e.g. UTCBrussels  – GPS time. These time differences, along with other information, are collected in a data format called CGGTTS and sent to BIPM. Using CGGTTS and other data, BIPM can compare a clock in Brussels with a clock in New York by subtracting the individual differences with GPS time: a technique known as “common view”.

UTCBrussels – UTCNew York = (UTCBrussels – GPS time) – (UTCNew York – GPS time)

The two GPS time terms above cancel each other out leaving the difference between UTCBrussels and UTCNew York.


Figure 2: By comparing individual clocks with GPS time, they can be compared with each other


Setting up a timing laboratory

To compare the atomic clocks used in timing labs around the world, they need to be connected to a GPS timing receiver. This is a special type of receiver that can use an external atomic clock instead of its own clock which is does using two output signals from the atomic clock:

  • a pulse every second synchronised to UTC (PPS IN) and
  • a 10 MHz frequency reference that is essentially a sine wave (REF IN)

The basic ingredients of a timing laboratory are shown in Figure 3. However, to reach the nanosecond accuracies required, a great deal of expertise and preparation are also needed. Signal delays in all elements in the setup should be accurately calibrated and for this, BIPM maintains a set of pre-calibrated travelling receivers as calibration references. As well as providing 1/3 of the timing receivers used for the calculation of UTC, Septentrio also provides BIPM with timing receivers for calibration.

Pushing the boundaries of science

Beyond defining and disseminating UTC, recent years have also witnessed GPS timing receivers staking their place at the forefront of science. In the case of the T2K experiment for example, by measuring precisely the transit time of neutrinos between two locations, limits can be placed on their mass thus shedding more light on the nature of these elusive particles.

At the other end of the size spectrum, the technique of VLBI (Very-Long-Baseline Interferometry) uses radio telescopes at distant locations which are linked together in networks by time-synching their observations using GPS common view. The resulting resolution is far in excess of anything that can be achieved by any single telescope on its own.

From the relatively mundane activity of time-stamping banking transactions to the truly extraordinary worlds of astronomy and high-energy physics, GPS technology continues to find new ways to improve our world and advance our knowledge of it.

The integrity program has an emphasis on ridding Corruption and Graft from all facets of the Provincial activity (Governance, Business and the Community). The Governor explained how introducing an integrity program was an enormous task; requiring education, participation, a change in thinking and a cultural change across the provincial community including the 20 municipalities. This will take time (maybe a generation) and education and persistence at all levels to achieve trust and integrity across the province.

There is an iSouth Catabato (integrity South Catabato) group consisting of 21 members (7 x Governance, 7 x Business and 7 x Community) meeting quarterly, to discuss and report on issues, and assess progress and acceptance. This group will focus on continuity and marketing to keep the plan alive and progressing into the future.

The BAC chairman and staff discussed the bidding process and explained the common errors and omissions that were common in purchasing and contracting;, this was aimed at helping local business to be more competitive and transparent in their bidding.
