THE SIMPLE ANSWER
Your Altus APS3G GNSS receiver is a high precision electronic satellite signal processor. When making a price comparison between Altus GNSS receivers and other brands; price is directly related to the hardware quality and the resulting precision and accuracy of the firmware operating the receiver in the receiver you buy……. YOU GET WHAT YOU PAY FOR!
Altus receivers have superior firmware algorithms developed in partnership with the Mathematicians, Geomatic Engineers and Programmers at the European Space Agency working with the Septentrio/Altus development team. This process is continuous.
Upgrades and improvements to Altus firmware are provided FREE OF CHARGE to all Altus receiver owners for the life of the product. Altus have the highest: speed of computation, and repeatable accuracy/precision of all receivers available on the market (5-8mm X&Y and 10-12mm Z). Septentrio, the mother company is working toward 3mm accuracy in the future.
GNSS receiver hardware is a collection of computer boards and radio signal processors designed to receive/send and disseminate radio signals from the GNSS (global navigation satellite system).
The warranty period provided by manufacturers is directly related to the quality of the manufacturing technique and repeat ability of the processes. The Precision of the manufacturing process in producing a reliable product with longevity determines the warranty period. Altus use robotic manufacturing processes to ensure 99.99% reliability and products are assembled by highly skilled technicians. There are no sweatshops in the manufacturing chain, unlike many products available today.
The “standard” Altus Warranty period for receivers is 3 years; for an addition charge this can be extended to 5 years. Most other manufacturers only provide 1 year warranty; this categorizing them as disposable equipment with limited life span.
All Altus receivers can be upgraded to current hardware and software specifications, The cost of upgrade is kept to a minimum (only a portion of original purchase price) making it possible to add new receivers to the surveyor/engineers existing GNSS system by upgrading the older receivers.
Your APS3G receivers are up-gradable using firmware to satisfy all GNSS development programmed through to 2015..
