Applanix announced a new version of its post-processing software for Mobile Mapping and Positioning, POSPac MMS version 5.4.



Applanix announced today a new version of its post-processing software for Mobile Mapping and Positioning, POSPac MMS version 5.4. Designed to enhance the productivity of Mobile Mapping, POSPac MMS 5.4 features an Inertially-Aided Precise Point Positioning (IAPPP) engine and enhanced smoothing algorithm.

The announcement was made today at INTERGEO 2010, the world’s largest conference on geodesy, geoinformatics and land management.

Precise Point Positioning (PPP) is an effective GNSS processing technique that uses precise clock and ephemeris information to converge to decimeter level position accuracy without base stations or expensive commercial SBAS subscriptions. It is an ideal and cost effective method of positioning for mobile surveys in remote areas or where centimeter level accuracy is not required. Traditionally, PPP techniques suffer degradation in accuracy following any loss of GNSS signal, requiring significant time for the solution to re-converge. Applying the Applanix IN-FusionTM techniques to PPP overcomes this by using inertial data to mitigate for signal outages and to retain full solution convergence.

This means:
  • Survey aircraft can fly sharp, high-banked turns to reduce time in the air  for increased productivity, without concern for degraded accuracy

  • Hydrographic survey vessels can obtain a decimetric accuracy PPP solution even when   operating in port environments or around offshore structures where GNSS signal outages may be common 

  • Land survey vehicles can lose full signal lock when passing under bridges and through tunnels   and still maintain converged PPP positioning accuracy after the outage 
POSPac MMS 5.4 also uses a new smoother algorithm for reverse time processing, greatly reducing or eliminating the position discontinuities associated with satellite constellation or fixed ambiguity changes. This is ideal for applications such as high-resolution mobile laser scanning which measure thousands of points per second.

“The IN-Fusion IAPPP technology in POSPac MMS 5.4 brings a new level of robustness to precise point positioning for mobile mapping applications,” said Edith Roy, Development Manager of POSPac MMS at Applanix. “The new software version continues the Applanix tradition of providing new and innovative products to our customers.”

POSPac MMS version 5.4 is available through the Applanix sales network, and to all POSPac users currently under a maintenance contract.
