However, one drawback with any precision L-Band signal such as H-10 is the time needed to converge on an accurate solution. Even with badly obstructed skies, for example near tree canopy during narrow river surveys, position tracking is solid. Using the Atlas L-Band correction service brings the benefits of multi constellation positioning to the CEESCOPEв„ў surveyor. With easy subscription ordering and receiver activation procedures, the Atlas system is convenient and budget-friendly. The Hemisphere Atlas L-Band approach allows the user to minimize capital investment in GNSS equipment, and only pay for required accuracy when needed. When fully converged, the H-10 signal will provide accuracy better than 10cm. The user may also later activate these subscriptions, or shorter period subscriptions for single projects. The H-10 signal may be activated at the factory for 1 year, 3 years or 5 years of L-Band signal. Vertical position data from Atlas BASIC is not accurate enough for incorporation into hydrographic datasets.ДЄ separate time-limited subscription to the Atlas H-10 L-Band correction service activates the multi constellation dual frequency L1/L2 receiver operation, and the Atlas corrections themselves. With 0.5m accuracy possible anywhere in the world, Atlas BASIC provides horizontal positioning accuracy adequate for most hydrographic projects.

Even for users in SBAS-enabled regions, the BASIC upgrade will provide better positioning quality through an increased number of satellites available for the solution the Atlas BASIC L-Band differential corrections can include multi constellation data not available to SBAS systems.ДЇor users in areas with no access to free SBAS signals, such as Africa, South America, Asia, and Australasia the Atlas BASIC provides a great positioning option and avoids the need to otherwise rely on 3m+ autonomous GPS quality. For a low cost вЂњlifetimeвЂќ subscription loaded at the CEE HydroSystems factory, the Phantom GNSS receiver is activated to receive L-Band corrections generated from HemisphereвЂ™s global network of over 200 reference stations. The Atlas BASIC upgrade adds key advantages. This configuration is appropriate for users in regions with free SBAS corrections (eg WAAS, EGNOS) and will allow submeter positioning without the need for any Atlas L-Band signal. The most basic CEESCOPEв„ў option has an advanced Phantom OEM GNSS receiver inside, ready to be activated for any of the L-Band services but it is supplied with no activation loaded. From the factory, CEESCOPEв„ў echo sounders may be configured as follows: So, the most basic CEESCOPEв„ў can be later upgraded to the highest performing option if necessary. All CEESCOPEв„ў systems are shipped with the multi constellation, dual frequency A42 antenna allowing users the ability to upgrade their positioning accuracy with no limitation caused by the antenna.ДЄll CEESCOPEв„ў echo sounders with built-in Phantom GNSS receivers may be configured by the user with any of the accuracy levels available, simply by loading a firmware activation file. Offering worldwide differential corrections broadcast from L-Band satellites over the equator, the Atlas system offers CEESCOPEв„ў users various levels of accuracy to suit the geographic location and the survey project requirements. The non-RTK CEESCOPEв„ў GNSS positioning solutions are based on the Hemisphere Phantom OEM receiver that can utilize Atlas L-Band corrections.

Top Images: Heavy sub-aquatic vegetation. For example, heavy bottom vegetation may be identified on the echogram and differentiated from the true bottom, a process that may be impossible with a basic echo sounder. When it comes to reviewing data quality in real time and after the survey is completed, the echogram record presents a crucial advantage over basic echo sounders that output only the digital depth sounding value. The intensity of the echo return from the entire water column and sub-bottom is recorded, not just the single sounding depth value for each ping. In addition to the sounding depth output, the complete sonar echo return from each ping is digitized into 3200 separate and discrete values from just below the surface to the sub-bottom level. The CEE ECHOв„ў and CEESCOPEв„ў echo sounders can log soundings at up to 20 Hz, providing exceptional bottom detail along the survey track.
