CONT

The Position and Azimuth Determining System(PADS) is a self-contained surveying system which provides fourth-and fifth-order control for U. S. [United States] Army Artillery surveys. The PADS is essentially a velocity aided inertial navigation system which has been designed to provide positional accuracy to 20 meters circular error probable(CEP) and height accuracy to 10 meters probable error(PE) over a 6-hour mission which starts at a "known" survey control point.

FV 514 véhicule d'observation d'artillerie.- En dotation dans les unités d'artillerie, il équipe les unités d'observation (Observation Post Vehicle ou OPV). Il est doté d'un mât avec un radar de surveillance et d'acquisition de cible (Man-packable Surveillance and Target Acquisition Radar ou MSTAR) ainsi que d'un système de positionnement et de détermination d'azimut (Position and Azimuth Determining System ou PADS). Il dispose aussi de systèmes d'intensification de lumière et de vision infra-rouge.

  • Mathematical Geography
  • Remote Sensing
CONT

Planimetric errors are often disregarded with the argument that they do not matter on flat surfaces. ... planimetric errors need attention when scanning systems are used to derive surfaces in rugged topography. Planimetric errors become the primary concern if objects are extracted from a cloud of laser points.

CONT

Our analysis reveals a planimetric positional error as large as 5 km for topographic features. It was found that the positional shifts are not systematic, and consequently, the shape of the terrain was geometrically distorted.

DEF

Erreur commise sur la position planimétrique d'un point, résultant de l'erreur graphique et exprimée en tenant compte de l'échelle du document.

CONT

L'INS [système de navigation par inertie] ou centrale inertielle est un appareil qui mesure les trois angles d'attitude de l'avion : lacet, roulis, tangage lors de l'émission laser. [...] L'INS génère principalement des erreurs planimétriques qui peuvent avoir un grand impact sur les erreurs altimétriques surtout en zone urbaine où l'on rencontre souvent des façades verticales.

The detection of an echo of a gamma-ray burst(GRB) caused by gravitational lensing is the only means of directly confirming the cosmological nature of bursts. The echo should appear within the same positional error box on the sky as the original burst, but will occur at a later time.

English

Subject field(s)
  • Volleyball
CONT

"Overlapping" is a positional fault. At the moment the ball is served, the back-line players must be behind their corresponding frontline player, the position of players being judged according to the positions of their feet.

OBS

Error in position of a player. When a team is found to be out of position, the play must be stopped and the error corrected. All points made by the team while in wrong position must be cancelled.

OBS

At the moment of service all players must be in specific positions. Once the ball is served players may move anywhere on their own side of the net. Any positional error is a fault and the offending side loses all points scored while at error, while their opponents retain all their points.

Key term(s)
