Since the establishment of International GNSS Service (IGS) stations, they have been used as control stations for assigning Precise point positioning (PPP) positions using one Global Navigation Satellite System (GNSS) receiver, which has increased from day-to-day. There are some factors affecting accuracy PPP positioning. This research aims to investigate relation between IGS distance and obser...

The most prominent spatially correlated errors in GNSS observations are well known to be atmospheric effects. ionosphere and troposphere the two main layers of Atmosphere that cause delays observations. A linear combination dual-frequency data can used reduce ionospheric delay. Unlike delay, tropospheric delay cannot eliminated using same methods. is primarily associated with GPS. it causes GPS...

André Hauschild ([email protected]) Title: Real-Time Clock Estimation for Precise Orbit Determination of LEO-Satellites Abstract: This paper/presentation discusses the real-time estimation of clock offsets for the GPS constellation. A realtime system for clock estimation is currently developed by DLR/GSOC to support up-coming missions which require precise orbit determination in near-real-...

Real time spectroscopic ellipsometry (RTSE) has been applied for in-situ monitoring of the first stage of copper indium-gallium diselenide (CIGS) thin film deposition by the three-stage co-evaporation process used for fabrication of high efficiency thin film photovoltaic (PV) devices. The first stage entails the growth of indium-gallium selenide (In1-xGax)₂Se₃ (IGS) on a substrate of Mo-coated ...

A trial was conducted to evaluate the effect of different cereals on the performance, gut mucosa, and microbiota of weanling pigs with or without previous access to creep feed during lactation. A total of 108 newly weaned pigs (7.4 kg BW; 26 d of age; half with and half without creep feed) were used. Piglets were distributed by BW into 36 pens according to a 2 × 6 factorial arrangement of treat...

Purpose: This research aimed to discuss the form and function of directive speech acts teacher students in online teaching learning interactions at SMP Ignatius Global School (IGS) Palembang. Methodology: The method used was descriptive qualitative, data source contained IGS. Results: Based on results, there were forms functions students’ acts. Furthermore, transactions found discourse classroo...

The nucleotide sequence of the intergenic spacer (IGS) between the 25S and 17S ribosomal RNA genes of Miscanthus sinensis var. glaber was determined. The spacer length (2,178 bp) in Miscanthus is close to that of rice IGS (2,140 bp). Many repeated elements with consensus lengths of 34 and 59 base pairs are found in the nontranscribed region (NTS), upstream of the putative transcription initiati...
