PPP/PPP‐RTK open formats: Overview, comparison, and proposal for an interoperable message

چکیده
Abstract This paper presents and reviews the main existing open specifications for PPP/PPP-RTK services, including satellite navigation providers (QZSS, Galileo, BeiDou, GLONASS) other industrial or scientific initiatives (RTCM, SAP-CORDA, 3GPP, IGS). To structure comparison, we adapted services to well-known OSI model defined them according their properties in communication layers. We show how proposed formats relate current standards, mainly RTCM SSR CSSR, what differences similarities are terms of transmitted corrections bandwidth. compare efficiency two scenarios: a global PPP scenario with multi-GNSS corrections, regional PPP-RTK scenario, also ionospheric corrections. propose an interoperable format that can be extension CSSR allows efficient transmission both global-scale MEO-based as well nationwide IGSO/GEO-based PPP-RTK.

متن کاملOpen standards, open formats, and open source
The paper proposes some comments and reflections on the notion of “openness” and on how it relates to three important topics: open standards, open formats, and open source. Often, these terms are considered equivalent and/or mutually implicated: “open source is the only way to enforce and exploit open standards”. This position is misleading, as it increases the confusion about this complex and ...
