Abstract. The emergence of single-frequency, navigation-type Global Navigation Satellite System receivers capable to provide carrier phase data [the so-called high sensitivity (HS) carrier phase positioning] has been steadily growing over the recent years. The main purpose of this study is to metrologically evaluate two low-cost, HS receivers, namely the u-blox LEA-6T and NEO-7P, in control surveying specifications. The evaluation was carried out within a published framework of standards and associated guidelines that are consistent with standards from the International Standards Organisation. The survey results were obtained from sufficient independent testing and proof and achieved an accuracy classification of '1 cm' at 95% confidence level. This indicates that the particular type of receiver used with geodetic antennas can provide positioning results for general purpose control surveying applications that are comparable to using geodetic receivers and with a significantly lower cost.

Precise positioning of an automobile to within lane-level precision can enable better navigation and context-awareness. However, GPS by itself cannot provide such precision in obstructed urban environments. In this paper, we present a system called CARLOC for lanelevel positioning of automobiles. CARLOC uses three key ideas in concert to improve positioning accuracy: it uses digital maps to match the vehicle to known road segments; it uses vehicular sensors to obtain odometry and bearing information; and it uses crowd-sourced location estimates of roadway landmarks that can be detected by sensors available in modern vehicles. CARLOC unifies these ideas in a probabilistic position estimation framework, widely used in robotics, called the sequential Monte Carlo method. Through extensive experiments on a real vehicle, we show that CARLOC achieves sub-meter positioning accuracy in an obstructed urban setting, an order-of-magnitude improvement over a high-end GPS device.

ABSTRACT. We report on ice movements changes in the Horcones Inferior Glacier (HIG), a major debris-covered glacier located in the southern sector of Mt. Aconcagua, Central Andes of Argentina. The HIG has been characterized by outstanding surge phenomena in the recent past, with the last episode registered in 2003. After a surge episode, the surface becomes highly unstable, with continuous ice degradation. We studied the response of the glacier surface in the post-surge stagnation period, based on six semi-continuous Global Navigation Satellite System (GNSS) stations distributed along the main axis of the glacier. Kinematic GNSS profiles were acquired over the surface, aiming to strengthen the GNSS measurements of elevation change. Our results show a horizontal surface displacement from 0.4 cmd -1 to 2.7 cmd -1 , and a 0.8 cmd -1 mean elevation reduction during the 2009-2014 period. GNSS profiles also show a velocity increase, ranging from -1.1 cmd -1 in 2012 to -1.8 cmd -1 in 2013. Changing surface velocities in the HIG may be related to the presence of a thick debris cover, in combination with faster glacier degradation due to thickness loss after the 2003 surge, and glacier-climate interaction.Keywords: GNSS, Debris-covered glacier, Change detection, Mt.

Adelgazamiento del glaciar cubierto Horcones Inferior, derivado de mediciones geodésicas mediante el uso de estaciones semicontinuas GNSS, durante un período de cinco estaciones de verano (C° Aconcagua, Argentina). En el presente estudio, se muestran los cambios de movimientos superficiales registrados por el Glaciar Horcones Inferior (GHI) el mayor glaciar cubierto localizado en el sector Sur del C° Aconcagua, Andes Centrales de Argentina. El GHI, se ha caracterizado por experimentar fenómenos de surges en el pasado reciente, cuyo último episodio registrado fue en el año 2003. Después de un episodio de surge, la superficie se comienza a suavizar mediante un continuo proceso de degradación del hielo. En este sentido, se ha estudiado la superficie del glaciar en el período de reposo postsurge, colocando seis estaciones semi continuas GNSS, distribuidas a lo largo del eje central del GHI. Además, perfiles cinemáticos GNSS fueron realizados sobre la superficie, con el objetivo de fortalecer y correlacionar las mediciones GNSS en el cambio de elevación. Los resultados muestran un desplazamiento horizontal de la superficie desde 0.4 cmd -1 a 2.7 cmd -1 , y una disminución en el valor de la elevación media de 0.8 cmd -1 , durante el período 2009-2014. Los perfiles cinemáticos GNSS arrojaron un incremento en la velocidad de decrecimiento en elevación desde -1.1 cmd -1 en 2012, a -1.8 cmd -1 en 2013. Cambios en las velocidades superficiales del GHI pueden estar relacionados con la presencia del espesor de la cubierta de detritos, en combinación con la rápida degradación que sufrió el glaciar después del surge de 2003 y también con la interacción del glaciar con el clima.
