RTK networks can provide an active service through the computation and transmission of error correction data to support the application of location-based services that require high accuracy positioning, e.g. land surveying, precision agriculture, machinery control etc. At present, the most used approaches to generate the NRTK (Network RTK) corrections are VRS (Virtual Reference Station) and MAC (Master Auxiliary Concept). In the Region of Murcia (SE Spain), two GNSS active networks (i.e. REGAM and MERISTEMUM) are available and they use MAC and VRS respectively. In order to analyse these RTK networks, four tests were designed and applied at five representative locations distributed throughout the Region of Murcia. The results indicate that both VRS and MAC solutions provide an accuracy within 2.5 cm in horizontal positioning and 5.0 cm in vertical positioning.

Due to the lack of research in the field of music through CLIL and ICT in Secondary Education in Spain, we propose to merge this subject with an innovative methodology. The general objective is to present a different approach to students in order to increase their motivation for the subject. The specific objectives are to teach music in English by integrating content, cognition and vocabulary through communication and the use of new technologies. This approach makes the design and implementation didactic, audiovisual and multimedia. Cuadernia: digital notebook composed of flash files, videos and audios, and gamification strategies. Quizziz: multiplayer questionnaire of class contents, based on teaching music through a cooperative methodology and gamification, are applied as options with a great educational projection, with information and innovative pedagogical experiences and potential to work together in the classroom with different levels of the subject. The results that follow the Likert scale reflect high student satisfaction with regard to teaching methodology, content acquisition, teacher training, ICT and resources. As a conclusion, of the coincident results between the professor and the students, we would like to implement it in the coming years.

Nowadays, the Continuously Operating Reference Station (CORS) network, combined with network RTK corrections (NRTK solution), is a widely used technique for high-accuracy positioning in real time. This “active” network realizes a reference frame and propagates it to the users. In border regions the coherence between the reference frames propagated by neighboring active networks is a critical problem. In this study the test results of post-processed and simultaneous NRTK positions at six test points located in the border region between Portugal and the Community of Andalusia, in the south west of the Iberian Peninsula, are presented. The analysis is based on two GNSS active networks present in this border region, namely RENEP (Portugal) and RAP (Community of Andalusia, Spain), a national and a local RTK network respectively, with similar characteristics. Upon comparing the post-processed position for each test point, as estimated with respect to each of the two active networks analyzed, the discrepancies found in 3D were less than 2 centimeters. The results of network-based RTK positioning were found to be successful within a 2 cm precision level in the east and north components and 4 cm for the up component. The results also confirm that the NRTK positioning accuracy is about 2 cm in horizontal and 4 cm in vertical, which can satisfy the requirement of real-time positioning users at a centimetric accuracy level, even in border regions considering extrapolated NRTK solutions.
