Thank you to Nlingi as always for these articles related to our work.
I would like to give attention to the following articles from June 2026 that I believe are related to IVS subject matter(s). I provide the DOI link, and a quick synopsis picked directly from the abstract/introduction of the article. If you have an article that you would like me to highlight, please let me know and I will update the list.

Title: Kinematic Phase-Referencing VLBI for Precise Positioning of the Tianwen-2 Probe
Doi: http://dx.doi.org/10.1029/2026RS008690
Synopsis: “To enhance the tracking precision of moving targets [like China’s Tianwen-2 probe], an improved Kinematic Phase-Referencing (KPR) VLBI method is investigated. By directly integrating a kinematic orbital model”Ŗparameterized by polynomial coefficients”Ŗinto the phase-referencing VLBI process, KPR-VLBI removes the need for the nearly constant-position assumption. Observations of the Tianwen-2 probe were carried out using the five stations of the Chinese VLBI Network to validate the KPR-VLBI method.” - Cite: Burt, et al. (2026)
Title: Frequency Standard Contributions to Limitations on the Signal-to-Noise Ratio in Very Long Baseline Interferometric Observations
Doi: http://dx.doi.org/10.1029/2025RS008476
Synopsis: “The coherence function is the metric usually used to determine the viability of a frequency standard. Here we show that [it] is a useful but not sufficient metric for gauging frequency standard performance in VLBI and instead derive an expression for the clock-limited VLBI visibility S/N. We evaluate this expression for real frequency standards and find only the Ultra-Stable Oscillator (USO) and hydrogen maser to be viable for upcoming high-frequency VLBI with the USO only useful for very limited integration times.”± - Cite: Timmerman, et al.

Title: Low-frequency VLBI with the SKA-Low
Doi: https://arxiv.org/abs/2606.25017
Synopsis: “We present the Low-frequency Australian Megametre-Baseline Demonstrator Array (LAMBDA) project: the construction of a several SKA-Low-like stations throughout Australia which can be employed to extend the SKA-Low’s baselines to the scale of megameters […] LAMBDA also serves to characterize the performance of the SKA-Low as part of a Very Long Baseline Interferometry (VLBI) network and by providing an early testbed for the calibration strategies which would be required.” - Cite: Xu, et al.

Title: SKA VLBI survey of the Southern sky for astrometry, geodesy, and astrophysics
Doi: https://arxiv.org/abs/2606.26745
Synopsis: “[The SKA VLBI] surveys will allow for doing geodesy with a Southern hemisphere-centered network, increase the density of compact radio sources that can be used as calibrators, further extend the celestial reference frame to deep south, and facilitate high-precision differential astrometry for a wide range of applications.”
