The X5 Mobile Pro is a GNSS receiver featuring cost-effective PPK, NTRIP, and RTK modes, designed to fit in your pocket, and delivering professional-grade performance. ULTRA-PORTABLE SIZE With an ultra-portable size of 84mm × 45mm x 15mm (without the HeliX5 multiband GNSS antenna and LoRa RTK antenna) and an ultra-light weight of 45 grams, users […]
In this article, we will explore in detail the step-by-step process of conducting a geotagged photo capture session using a METTATEC model X5 MOBILE high-precision mini GNSS receiver with NTRIP corrections, in combination with a smartphone equipped with a high resolution digital camera.
In the realm of drone surveying, accuracy is the cornerstone of successful data collection. Among the diverse array of tools available to enhance surveying precision, GNSS receivers play a pivotal role. In this ecosystem, the new METTATEC X5R PLUS GNSS receiver with LOCAL NTRIP offers clear advantages in the field, compared to other GNSS products […]
It is essential to acknowledge the importance of price or purchase value within the Topography and Geomatics equipment market. Therefore, this time we decided to share information about GNSS data capture using low-cost devices, as these have gained significant acceptance in the market. The demand for centimeter-level accuracy in various applications has been fueled by the increasing availability of low-cost GNSS chips in the mass geolocation market.
GIS Applications for Data Collection with Smartphones A Geographic Information System (GIS) is an environment for collecting, managing, and analyzing data. GIS applications for data collection in the field using smartphones analyze spatial location and organize layers of information into visualizations using maps and 3D scenes. With this unique capability, GIS reveals deeper insights into […]
Now it is possible to achieve centimeter accuracy in smartphones or tablets with the X5 Mobile, a high-precision GNSS receiver that works connected to a cell phone or tablet with Android or Windows operating systems and has two correction options: PPK and NTRIP that receives data through the device’s Internet connection using a USB or Bluetooth connection.
What is NTRIP? NTRIP is the transmission of satellite navigation data over the Internet. NTRIP is the acronym for Networked Transport of RTCM via Internet Protocol, which refers to the transport of a data network in RTCM format via Internet protocol. In this article we will explain what NTRIP positioning consists of and what are […]
What are Photogrammetric Support Points and what is their relationship with RTK/PPK Drones? The PAF: Photogrammetric Support Points, or also known as GCP (Ground Control Points in English) are those points that are used to adjust the photogrammetric block. On this occasion, we will study its relationship with RTK/PPK Drones. The PAF coordinates will allow […]
Cartographic Projections Cartographic projections are those mathematical transformations that allow to represent and project a spherical shape in a plane, and convert the geographical coordinates, which are latitude and longitude, into Cartesian coordinates (x, y). These coordinates arise from the need to be able to capture the earth’s surface on a flat surface with as […]
Definition and Usefulness In general, GNSS geopositioning satellites emit signals consisting of three parts. A carrier signal, one or more pseudorandom noise codes (PRNs), and a navigation message. The last two are modulated by the carrier using a technique known as phase modulation. LGNSS channels allow the antenna of a GNSS receiver to detect the […]
